Throughout history, humankind has been constantly traveling for various reasons. Highway transportation is often preferred for these trips. However, traveling by highway is a tiring and time-consuming form of transportation and it is relatively more difficult and complicated compared to other transportation alternatives (seaway and airline transportations). Because people who travel should rest at regular intervals to meet their physical or physiological needs. Rest areas are critical places to meet such needs while traveling. However, people encounter many different resting places along the travel itinerary. The fact that there are many places that can be used to meet their needs, confronts consumers with the decision problem. In this study, it was aimed to determine the factors affecting the preferences of consumers among the many resting places encountered and the importance levels of these factors on the resting place preference. The data were evaluated by using the widely used Analytical Hierarchy Process (AHP) method of decision theory and it was determined that the most important factor affecting consumer choice was the “services” provided at the resting area.

This paper derives a mathematical relationship between the shape information of an object and their discrete cosine transform (DCT) coefficients. Here, each column of the object is put into a matrix. As the lengths of different columns in the object are different, the lengths of the columns of the matrix are reset to the maximum value among these lengths of the columns of the object and the rest elements in the columns of the matrix are set to zero. The mathematical relationship between the shape information of the object and the DCT coefficients is derived. By substituting the DCT coefficients in the derived model, the shape of the object can be obtained directly in the DCT domain. Since most of the images are coded in the DCT domain, the derived result can significantly improve the efficiency for identifying the objects.

The goodness of fit of first motion manually picked polarities from the reviewed Bulletin of the International Seismological Centre (ISC) is examined versus available earthquake mechanism solutions in order to study the behavior of seismic stations, and/or reporting agencies, over time. The probability of the reporting polarity data fitting (and not fitting) source mechanisms is quantified by calculating the probability distribution of several Bernoulli trials over a randomly perturbed set of hypocenters and velocity models for each earthquake mechanism–station polarity combination. The overall agreement of first motion polarities against source mechanisms is found to be good with a few cases of seismic stations showing indications of systematic phase reversals over certain time periods. Specifically, results were obtained for 50% of the registered stations at the ISC, and from these stations 70% show reliable operation during the operational time period under investigation, with only 3% showing the opposite, and 7% showing evidence of systematic changes in the quality of the reported first motion polarities. The rest showed great variability over short periods of time, which does not allow one to draw any conclusions. Comparing waveform data with the associated reported polarities revealed a mixture of cases of either questionable picking or true station phase reversals. The ISC is planning to make available on its website the detailed results for each station in order to make data users and seismic network operators aware of cases that need attention.

This study focused on investigating differences in shooting performance and performance-related factors between two different aiming strategies (HOLD, low radial velocity during the approach 0.4-0.2 seconds before triggering, and TIMING, high radial velocity) in biathlon standing shooting. A total of 23 biathletes fired 8 × 5 standing shots at rest (REST) and 2 × 5 shots during a race simulation (RACE). Shooting performance (hit point distance from the center of the target), aiming point trajectory and postural balance were measured from each shot. Shooting performance was similar both at REST (HOLD 33 ± 5 mm vs TIMING 38 ± 8 mm, P = .111) and in RACE (40 ± 11 mm vs 47 ± 12 mm, P = .194). Better shooting performance was related to smaller distance of the aiming point mean location (REST r = 0.93, P < .001, RACE r = 0.72, P = .018) and higher time spent within ⅔ of the distance of the hit area edge from the center 0.6-0.0 seconds before triggering (REST r=-0.88, P = .001, RACE r=-0.73, P = .016) in HOLD, and to lower aiming point total velocity 0.6-0.0 seconds before triggering (REST r = 0.77, P = .009, RACE r = 0.88, P = .001) and less aiming point movement 0.2-0.0 seconds before triggering (REST r = 0.82, P = .003, RACE r = 0.72, P = .012) in TIMING. Postural balance was related to shooting performance at REST in both groups and in RACE in TIMING. Biathletes using the hold strategy should focus on stabilizing the aiming point before triggering and aiming at the center, whereas biathletes using the timing strategy benefit of decreasing the total velocity during the final approach as well as minimizing the aiming point movement right before triggering.

We wish to fix an error in [1] . The list of representatives of the isomorphism classes of skew-symmetric products μ : g × g → g for a complex 3-dimensional vector space g given there in Proposition 3.5 corresponding to the rank-2 degenerate products characterized by (2) in Proposition 3.3, were collapsed into a single representative, whereas a one-parameter family of representatives should have been obtained, as it is well known from the classification of 3-dimensional Lie algebras. The mistake affects the statements of Propositions 3.5 and 5.4. This note gives the correct statements of these two results. The rest is unaffected.

According to the Kripke-Putnam orthodoxy, a term like 'water' refers to samples of the same substance as the items on the basis of which the term was introduced. However, observations due to Needham (2000) and Leslie (2013) cast doubt on the idea that there is a uniquely privileged notion of substance relevant to the determination of reference, in which case it would seem at best indeterminate what the word `water' refers to. In response to this problem, Gomez-Torrente (2019) has argued that there is a privileged notion of substance that plays a role in the determination of reference, namely, the ordinary notion of substance. This paper argues that Gomez-Torrente's proposal is not successful. Contrary to what Gomez-Torrente supposes, there is no uniquely privileged ordinary notion of substance; rather, there are many notions of substance compatible with the meaning of 'substance' none of which seems privileged over the rest.

Antoine Brumel’s Missa pro defunctis is one of the earliest polyphonic Requiem settings, and the first by several decades to include the sequence, Dies irae. Whereas most chants in the Mass for the Dead were set c.1500 to the low-pitched, highly consonant polyphony that denoted mourning and penitence at the time, the Dies irae is a musical portrayal of the Last Judgement that might seem to demand more vivid polyphonic treatment. And yet Brumel’s setting, a grand alternatim movement, responds more to the formal regularity of the chant than to its text, which describes a terrifying scene much like what is seen in contemporaneous visual depictions of the Last Judgement. Indeed, Brumel’s most striking rhetorical moment comes not in the frightening early verses of the sequence but in its concluding plea to Christ that the dead be granted peace. Analysis of Brumel’s Dies irae in the context of his Missa pro defunctis, therefore, shows that early Requiem compositions, even at their most terrifying, serve first and foremost as functional pleas to God that the deceased be granted eternal rest and perpetual light.

This paper presents a thorough review of new data and research on the Neolithic and Bronze Age periods in Epirus. It correlates new with old material in an attempt to outline the situation in Epirus and to highlight the region’s peculiarities. These peculiarities make Epirus attractive for scholars and at the same time set it apart from the rest of Greece. The ultimate goal is to reconsider Epirus’ position in the field of Greek and European prehistory more broadly.In memory of my beloved father Dimitris

The theological problem underlying environmental and gender injustice is the pathological assumption that “the rest of” creation is available for use and commodification by a select group of privileged image bearers. An adequate response to this assumption requires re-examining appropriate relationships between creatures. The story of Hagar’s relationship to water provides the foundation for such a response. An ecomimetic interpretation of Genesis 16:1–16 and 21:8–21, focused on the character of water in these passages, uncovers the basis for an appropriate human relationship to water that challenges the ways in which both water and women have been commodified.

As an international team (US and Spain), we write these words while both our countries and the rest of the world are in the throes of a pandemic. We are all social-distancing, and the normalcy we once took for granted has shifted dramatically, leaving us to struggle to find our equilibrium. The shift has been significant for every aspect of life, particularly for educational institutions. For many, this quick transition has not been a smooth one as the means to execute high-quality online education are somewhat limited and require systems to adapt quickly. We will use this commentary to outline some of our thoughts amidst this unprecedented time and to explore social media, the pandemic, pitfalls, and possibilities as we move forward into new futures.

We explore the persistence of the alignment of brightest cluster galaxies (BCGs) with their local environment. We find that a significant fraction of BCGs do not coincide with the centroid of the X-ray gas distribution and/or show peculiar velocities (they are not at rest with respect to the cluster mean). Despite this, we find that BCGs are generally aligned with the cluster mass distribution even when they have significant offsets from the X-ray centre and significant peculiar velocities. The large offsets are not consistent with simple theoretical models. To account for these observations BCGs must undergo mergers preferentially along their major axis, the main infall direction. Such BCGs may be oscillating within the cluster potential after having been displaced by mergers or collisions, or the dark matter halo itself may not yet be relaxed., In press, MNRAS

Re-activations of task-dependent patterns of neural activity take place during post-encoding periods of wakeful rest and sleep. However, it is still unclear how the temporal dynamics of brain states change during these periods, which are shaped by prior conscious experiences. Here, we examined the very brief periods of wakeful rest immediately after encoding and recognition of auditory and visual stimuli, by applying the EEG microstate analysis, in which the global variance of the EEG is explained by only a few prototypical topographies. We identified the dominant brain states of sub-second duration during the tasks-dependent periods of rest, finding that the temporal dynamics-represented here by two temporal parameters: the frequency of occurrence and the fraction of time coverage-of three task-related microstate classes changed compared to wakeful rest. This study provides evidence of experience-dependent temporal changes in post-encoding periods of resting brain activity, which can be captured using the EEG microstates approach.

An optimal control problem is solved for a two-body limbless locomotor crawling along a straight line on a horizontal rough plane. Coulomb’s dry friction acts between the locomotor’s bodies and the underlying plane. The control is performed by the force of interaction between the bodies. The system should be moved from the state of rest by a given distance in a minimal time, provided that the relative positions of the bodies in the initial and terminal states coincide and the velocities of the bodies at the terminal instant are equal to zero. A particular attention is given to the case where the bodies are prohibited to change the direction of their motion.

OCCUPATIONAL APPLICATIONSDesigning sustainable cyclic work requires attention to both the workload amplitude as well as the duty cycle, the fraction of the work cycle with active workload, that therefore also defines the recovery phase of the cycle. A number of different approaches and models have been developed to calculate the required recovery time for a given load and duty cycle. We present a comparison of three types of models at the "breakpoint" that defines the boundary of load amplitude and duty cycle where fatigue begins to accumulate faster than recovery allows within the work cycle. This comparison shows considerable variation between models of the "allowable" load or duty cycle depending on the method used. Practitioners should thus be cautious applying these models indiscriminately in job design as their results can vary substantially. In particular, differences between the tasks used for model formulation and application may compromise validity, and model application in a given context should be verified before broad application.TECHNICAL ABSTRACT

There are many methods of building patterns , but there are two basic methods, the flat method and modelling on dress-standmethod, the flat method is a method for drawing patterns using foundations and mathematical methods in the form of measurements that represent the human body and are in the form of lengths and perimeters on the basis of a two-dimensional concept although the body is a template Three-dimensional . The modelling methodis characterized by the uniqueness among the methods of preparing the patterns, where the designer or the preparer of the pattern formed the fabric on the dress stand through successive steps, modifies it, evaluates its steps and improves it, depending on his skill and his Abandonment ability until the fabric is transformed into a 3D shape . In addition to preparing patterns, the modeling method is used as a way to make adjustments "rehearsal " to the clothes that were manufactured by paper patterns , which indicates its inaccuracy. The modifications made to the paper pattern are an attempt to change some lines that do not match the shape of the body to become identical to it. The paper patterns still needed tomodify until the middle of the nineteenth century, so clothing makers resorted to developing them by combining the modelling method and the paper pattern method by using the industrial body. Most pattern designers make the pattern by combining the modelling method and the flat method, where the pattern is built first in the flat method and then placed on the dress stand or human body to make the necessary adjustments to it. The collar plays an important role in the general shape of theuniform, as it is considered one of the most important parts of the clothing because of its effective role, as it either emphasizes the elements of beauty in the clothes or from the reasons for reducing these elements or spoiling the appearance; It must be given special attention in all stages of its production.Problem : Through the researcher's work in teaching many pattern courses for the students of the Garment and Textile Division and other divisions in the college, I noticed that there is no way to build paper patterns for many of the composite techniques that are unique to the modeling method without the rest of the other methods for preparing patterns, and among these techniques are some of collars designs Used in womens coats; Hence the idea of the research, which is an attempt to propose new paper patterns (for some designs of collars that are difficult to build in the flat method), which is derived from the patterns formed on the dress-stand . Objectives : 1- Attempting to obtain a proposed flat method for constructing some collars patterns that can only be constructed by the modelling on dress-standmethod. 2- Contributing to developing new flat patterns for collars other than the traditional models. Methodology : The research follows the semi-applied approach to suitability to achieve the research objectives and verify its hypotheses. Results: - There are statistically significant differences between the fitting levels (appropriate - to some extent - not appropriate) for each of the three designs, where the adjustment (appropriate) was achieved in the designs at rates higher than (90%) against very small ratios for lack of fitting (not appropriate) in Some elements do not exceed 1.4%. - There are no statistically significant differences between the sizes used in a single design, meaning that the degree of control of the proposed

In the present paper, we discuss the notion of “tropical mathematics” in view of the fact that, up to the present time, there is no generally accepted correct understanding of this notion. The paper presents, rather than mathematical proofs, humanitarian and social justification of the correct understanding of the term. The author proposes to describe the term “tropical mathematics” by means of a frame based on linguistic, psychological, and cognitive considerations. As an example of the new reality to which tropical mathematics can be applied, one can consider the group of the richest men on our planet, say those who appear in the corresponding lists of the American financial journal “Forbes.” Once a person has joined this group, he has reached a different state and will have special relationships with the rest of the world. To support the claim that tropical mathematics is in a sense “fantastic”, we shall present some unexpected viewpoints of this science. It will also be shown that in tropical mathematics such classical mathematical principles as the Duhamel principle or the Fredholm alternative remain valid.

Friction is one of the types of interaction between bodies. It occurs when two bodies touch. The forces acting between the surfaces of contacting solids are called dry friction forces. They are always directed tangentially to the touching surfaces and are divided into the forces of friction at rest, sliding and rolling. The friction forces depend on many factors that accompany the movement of bodies in the presence of friction. In this regard, the description of friction forces is possible only with the help of empirically found approximate laws, which are often quite rough. The rest friction force is a variable value, it can change from zero to a certain maximum value. By applying a force to the body that exceeds the maximum resting friction force, we will move the body from its place, and it will begin to move. The article considers examples of motion in which the friction force can be mistakenly interpreted as a driving force. The nature of the forces of friction at rest and rolling is considered from the perspective of modern physical materials science.

A linear wave equation with acoustic boundary conditions (ABC) on a portion of the boundary and Dirichlet conditions on the rest of the boundary is considered. The (ABC) contain a memory damping with respect to the normal displacement of the boundary point. In this paper, we establish polynomial energy decay rates for the wave equation by using resolvent estimates.

The tourism sector is a fast-growing contributor to the global economy, and nature-based tourism (NBT), particularly in Asia and Africa, is booming. Through the creation of jobs and revenue NBT has the potential to combat deforestation in regions that are economically poor, but of high biodiversity value. Inspired by the success of gorilla tourism in Uganda and Rwanda, several gibbon tourism projects have been initiated in Southeast Asia and China. Despite the existence of these programmes, no research has been done to investigate the impact of tourism on the behaviour of gibbons. To address this, we collected observational data on a group of northern yellow-cheeked crested gibbons (Nomascus annamensis) at Veun Sai-Siem Pang National Park (VSSPNP), Cambodia, in the presence and absence of tourists. We found there was a significant increase in the amount of time individuals spent scanning their environment and travelling at the cost of rest when in the presence of tourists. We also found that individuals were significantly more likely to self-groom in the presence of tourists. These results highlight the importance of scientific research in implementing successful, low-impact NBT programmes that consider animal behavioural changes. We are continuing to collect data on gibbons at VSSPNP and at Mt. Gaoligong National Nature Reserve, China with the aim of extending the IUCN’s best-practice guidelines for great-ape tourism to include the small apes.

Domain-Specific Languages (DSLs) are programming languages designed specifically to express solutions to problems in a particular domain. It is said they foster productivity and quality. In this work we describe CRUDyLeaf, a DSL focused on the generation of Spring Boot REST APIs from entity CRUD operations. Spring Boot is an open source Java-based framework used to implement the REST architecture style. It has gained popularity among developers mainly because it allows to build stand-alone and production ready software applications (avoiding the use of an application server). Through seven proposed stages (domain immersion, golden application implementation, syntax definition, meta model generation, code generator implementation, deployment, and refinement) we describe the development of this DSL. We also exemplify and evaluate the proposed DSL. Our findings suggest a yield automation rate of 32.1 LOC (Lines Of Code) for each LOC written in this DSL, among other observed benefits.

The synthesis problem is to construct a system fulfilling some specific requirements when interacting with the environment, which is one of the most crucial and challenging tasks in robotics. In comparison to the case of dealing with a single robot, synthesizing of a system constituted with multiple robots is, in general, much more involved. Actually, information is shared among robots in the latter case, and for a fixed robot, when fictively merging the rest ones into its environment, we are confronted with imperfect description of environments. In this article, we present an iterative controller synthesis approach to dealing with multirobot systems. In our model, the behaviors and outputs of one robot can be observed by the other ones, as a part of their inputs. To make our model more flexible, we allow the mechanism of “partial observation,” namely, only a part of outputs can be observed by other robots on some particular sensors. Our synthesis approach is conductive in an iterative manner. By analyzing the dependence among robots, we first try to synthesize controllers for some of them and then extract a set of invariants from the solved part to refine other ones. Repeatedly and iteratively using this way, we may arrive at a complete solution. Meanwhile, in comparison to the monolithic approach, using the iterative manner usually produces a much more compact result, which means that the size of the controller is smaller.

The aim of the study was to compare the performance of two data exchange styles commonly used in web applications, i.e. REST and GraphQL. For the purposes of the study two test applications were developed containing the same functionalities, one of which was REST and the other one was GraphQL. They were used for performance tests done with the help of the JMeter tool, during which measurements of the total processing time of requests and the volume of data downloaded and sent were performed. An experiment was developed that tested the basic operations found in most network services: display, add, update, and delete data. The most attention was devoted to the information display operation in the case of which load tests were done. On the basis of performed studies and obtained results, no differences in performance during the operation of adding, editing and deleting data by applications based on REST API and GraphQL were found. During the display operation under heavy load conditions and while downloading small portions of data, the service using GraphQL had a better performance. When downloading large portions of data, the REST-based service exhibited a higher performance.

A good application development requires a testing phase to ensure there are no errors before it’s released to public. But testing phase becomes difficult if the application development involves features from third parties. The idea to resolve the problem for Dhanapala application under the auspices of PT. Semangat Gotong Royong is to make the Sandbox system which is a system designed to resemble the characteristics of a third party. The Sandbox system will be developed into a REST API and written using the Golang programming language. In conducting communications with other systems New Simple Queue (NSQ) is also used that can support concurrency and prevent data transmission failures. As a result, the Sandbox system can receive requests and will process responses that are similar to functions from third parties. All forms of feature calls to third parties can be transferred to the Sandbox system so that all the data needs on some functions involving third parties can be fulfilled and the Dhanapala application can be run without its dependence on third parties

The concept of ‘force’ is abstract and challenging for many physics students, and many studies have revealed misconceptions that hinder students’ understanding and learning in classical physics. One reason for this may be the multifaceted nature of the concept and how textbooks give different definitions and explanations depending on the context. In this article, we present a framework of eight categories for how the concept is described, based on fundamental principles in physics, their historical sources and an analysis of how ‘force’ is described in four physics textbooks used in upper secondary schools in Norway. Examples from one of the textbooks that constituted the empirical basis for the framework are given. These reveal that textbooks may present students with a variety of definitions and explanations of ‘force’. It is argued that students should be made aware of this variability in order to support their motivation and learning in physics, but also to understand the complex and evolving nature of the force concept and other important concepts in physics.

In the nonrelativistic approximation of fluctuation electrodynamics, using the specular reflection model and the nonlocal dielectric permittivity of a metal, simple analytical expressions are obtained for the friction forces in the particle-plate and plate-plate configurations at relative motion of bodies with constant velocity. It has been shown that at distances of about 1–10 nm, for an Au nanoparticle (or a gold plate) moving near another similar plate at rest, the dissipative forces are 2–4 orders of magnitude higher than when using the Drude local dielectric function.

Multiple determination is the epistemic strategy of establishing the same result by means of multiple, independent procedures. It is an important strategy praised by both philosophers of science and practicing scientists. Despite the heavy appeal to multiple determination, little analysis has been provided regarding the specific grounds upon which its epistemic virtues rest. This article distinguishes between the various dimensions of multiple determination and shows how they can be used to evaluate the epistemic force of the strategy in particular cases. Distinguishing between the various dimensions helps to resolve the disagreements regarding the relevance and epistemic import of multiple determination for scientific research. It also suggests a fruitful mode of interaction between the philosophy of science and (historical) accounts of scientific practice.

This investigation used image data generated by an anthropomorphic phantom to determine the minimal 99mTc rest-stress activity concentration ratio (R) able to minimize the ghosting effect in the single-day stress-first myocardial perfusion imaging, using different positions of the perfusion defect (PD), scanners and reconstruction protocols. A cardiac phantom with a simulated PD was imaged under different R using different gamma cameras and reconstruction algorithms. The residual activity from precedent stress administration was simulated by modeling effective half-times in each compartment of the phantom and assuming a delay of 3 hours between the stress and rest studies. The net contrast (NC) of the PD in the rest study was assessed for different R, PD positions and scanner/software combinations. The optimal R will be the one that minimize the NC in the rest images The activity concentration ratio R, the position of the PD and the scanner/software combinations were all main effects with a statistically significant impact on the NC, in decreasing order of relevance. The NC diminished significantly only for R values up to 2. No further improvement was observed for NC for R values above 2 and up to 3. NC was significantly higher in anteroseptal than in posterolateral positions of the PD and higher for solid-state cameras. A rest-stress activity concentration ratio R of 2 in single-day stress-first myocardial perfusion imaging is enough to achieve the maximum net contrast in the PD. This ratio should be used to optimize patient’s radiation exposure.

Introduction. The article is devoted to the description of the shedule development particularities and a drivers’ work and rest schedule adjustment in an organized children carriage considering their age in an intercity connection. During the interurban transportation after first four hours and thirty minutes of uninterrupted driving, a special break for the rest is provided for drivers on the way lasting at least 45 minutes. This period can be divided into two or more parts, but the first part should last at least 15 minutes and the last one at least thirty minutes. At the same time children of different age groups perceive long distant travels variously due to their physiological development. The restriction of physical activity during a long time may have a negative impact on children’s physical and mental state. Children may have some problems with behavior control during long distant travels, it may lead to a travel rules violation, they remove their seat belts, start to walk around the bus, etc. The dependencies of the covered distance and time on a children’s age were identified based on the study results of the intercity children carriage process. The findings may be applied in a bus route timetables development, a drivers’ work and rest schedule adjustment during an organized children carriage in an intercity connection and also when planning transport infrastructure objects along popular tourist routes or frequently used transportation directions for students.The purpose of article is the description of a traffic schedule particularities development and a drivers’ work and rest schedule adjustment in an organized children carriage considering their age in an intercity connection. The scientific novelty lies in methodology used for a drivers’ work and rest schedule adjustment which depends on a distance and travel time in an organized children carriage by buses in an intercity connection and on the age of the carried children.Materials and techniques. While writing the article the methods of a passengers carriage theory, a statistical and systematic analysis, a transport process theory and also some other scientific methods and techniques were used.Results. The results have advisory nature and are proposed for use in a drivers’ work and rest schedule adjustment in an organized children carriage considering their age in an intercity connection.Discussion and conclusion. For the carriage of different aged children the scheme of traffic according to a children age group should be chosen. 4 age groups of children each of which correspond to a certain traffic and rest time on the way were identified during the study.

Non-invasive measurement method has made rapid developments in the field of biomedical engineering. One of research is impedance cardiography (ICG), which provide information of pulsation basic. By knowing this kind of measurement technique, it will assist inspection of the patient's physiological condition with cardiovascular system. This research is aimed to determine the mechanical characteristics of the cardiovascular system in the human body such as a wave graph of pressure, flow, and volume, based on pressure–flow model in rest condition, and analyze the simulation results by implementing state of the physiology cardiovascular disease. To obtain the wave chart that is modeled by the cardiovascular system using a lumped parameter method, formulate the differential equations of the pressure–flow dynamics equation for an incompressible fluid in a segment of a cylindrical elastic tube and simulate the model using the Simulink toolboxes from Matlab R2008b. The simulation with lumped parameter method resulted wave graphics of pressure, flow, and volume of physiological state a person in rest condition, the left ventricular pressure is 120 mmHg , right ventricular pressure is 30 mmHg , left ventricular outflow is 800 mL / sec and volume in the left ventricle is 160 mL . By implementing the simulation have been developed on the physiological state of cardiovascular disease, hypertension occurs when the arteries resistance R3i = 0.61 mmHg × s mL with the pressure of the left ventricle is 145 mmHg. For coronary heart condition, ventricular pressure decreased until 82 mmHg in the value of the coronary arteries resistance is R3o = 0.852 mmHg × s mL. This research assumed heart haves the character of passive because there is no feedback signal that can compensate if the pressure in the systemic circulation is reduced. The research can be concluded that the graph from simulation shows the results are not much different from the reference chart, this results indicates that the equation and the simulation was able to reflect on the human circulatory physiological circumstances. A little different of a graphic simulation result due to differences in the parameters and assumptions used.

This research is a critical study of tourism at four cemeteries in the Los Angeles area between 2013 and 2019: Hollywood Forever, Forest Lawn in Glendale, Forest Lawn in Hollywood, and Pierce Brothers Westwood Village Memorial Park Cemetery. We examined these venues through the lens of celebrity tourism, since they are known as "Hollywood memorial parks," hosting the graves of some of the most famous stars in the world. Through participant observation, informal conversations, and content analysis of texts we aimed to understand how the relationship between these venues and the entertainment industry works as a "pull factor" for tourists. Our data collection and analysis led to three main findings. Firstly, we identified the motivations behind the increasing number of tourists who add Los Angeles cemeteries to their must-see list. Although scholars often define cemeteries as dark tourism destinations, our investigation shows that Hollywood memorial parks are more related to celebrity tourism. Secondly, employing the notion of "cult of celebrity," we described how the experience of tourists visiting their favorite celebrity's grave can be seen as a modern pilgrimage centered on a collective experience. Thirdly, we analyzed the cemetery as a commodity in which executives work to promote the site as the perfect location where one can spend the "eternal life." In this sense, we also investigated how memorial parks are often used as venues for cultural events, attracting a large number of tourists. As described in the findings section, initiatives such as movie screenings and guided tours transform cemeteries into much more than just peaceful places where to honor the dead, becoming venues for both commodification and spectacle.

In 1982, Julio Cortazar and Carol Dunlop commenced a thirty-three-day journey from Paris to Marseille in which they promised to never leave the autoroute and to stop at every single rest stop. The ...

According to Genevieve Lloyd, conatus is manifested in body as a fixed ratio of motion and rest and in mind as increasing adequate understanding. The commentary provides textual analysis to resolve...

We analyze here the changes that may occur in the length of a rod due to Lorentz contraction, when the rod, initially stationary in one inertial frame, is accelerated so as to come to rest in another inertial frame. The rod that earlier appeared shorter due to the Lorentz contraction in one frame should later appear shorter in the other frame. Has the rod length been reduced during acceleration, as might appear in one of the frames, or has it expanded as may seem in the other frame? What exactly lies behind the genesis of Lorentz contraction during an acceleration? Actually, the accelerations at two ends of the rod, even if applied simultaneously in one frame, may not seem so in the other frame. This, in turn, may result in a lengthening or shortening of the rod in a frame, depending upon the relative timings of accelerations applied, e.g., whether the accelerations applied at the rod ends were non-simultaneous in that frame and, if so, which end started getting accelerated earlier than the other. Of particular interest is the case where the rod transits through a series of inertial frames, with a constant proper acceleration in each successive instantaneous rest frame. The rod could then be considered to be stationary in a comoving accelerated frame. In this case, the applied acceleration may everywhere be temporally constant; however, it will spatially vary along the length of the rod. Strange though it may appear, all sections of the rod, in spite of their differential accelerations, come to rest simultaneously in each inertial frame, with no change in the proper length of the rod in successive frames.

This paper proposes a robust three-dimensional cooperative guidance law (RTCGL) against a maneuvering target. When some missiles are intercepted during the engagement, this RTCGL integrated with a local filtering algorithm can ensure that the rest missiles hit the maneuvering target simultaneously. The pitch acceleration command is designed based on an augmented proportional navigation guidance law and can make the missile’s trajectory fall into its yaw plane. Then the three-dimensional cooperative problem is converted into a planar one. The yaw acceleration command consists of a guidance component for homing and a coordination component for simultaneous arrival. Numerical simulation results are presented to verify the effectiveness of the cooperative guidance law.
