Sports employ computer vision for a variety of applications, including interactive viewing, object interpretation, sports action analysis, and intelligent rule-based systems for better referee choices. The computer vision problem known as “sports action recognition” looks for interactions between players and related sporting items. Most of the existing solutions in sports action recognition are complex and incomplete as taking both playfield and non-play field objects with various actions for the same human posture into account. Hence, the proposed model focuses only on objects within the playfield and the right functional action that is performed by the human. We identify the play field using a quadrant-based density (QD) approach which locates the crowded region and then morphological operations are applied to spot only play region. The right action performed is identified using the logic-based query to the Sports Action Generation model (SAG) which is generated using the newly constructed sports ontology. The proposed semantic verification model using ontology typically offers more transparency compared to deep learning networks. It relies on explicit rules and logic that can be easily interpreted, enhancing interoperability and accuracy across systems. We use the sports video wild (SVW) and UCF-101 datasets to assess the performance of our proposed model. The proposed sports action recognition system achieves action identification in videos with a good accuracy of 96%.

The design and construction of CARMENES has been presented at previous SPIE conferences. It is a next-generation radial-velocity instrument at the 3.5m telescope of the Calar Alto Observatory, which was built by a consortium of eleven Spanish and German institutions. CARMENES consists of two separate échelle spectrographs covering the wavelength range from 0.52 to 1.71¿m at a spec-tral resolution of R < 80,000, fed by fibers from the Cassegrain focus of the telescope. CARMENES saw ¿First Light¿ on Nov 9, 2015. During the commissioning and initial operation phases, we established basic performance data such as throughput and spectral resolution. We found that our hollow-cathode lamps are suitable for precise wavelength calibration, but their spectra contain a number of lines of neon or argon that are so bright that the lamps cannot be used in simultaneous exposures with stars. We have therefore adopted a calibration procedure that uses simultaneous star / Fabry Pérot etalon exposures in combination with a cross-calibration between the etalons and hollow-cathode lamps during daytime. With this strategy it has been possible to achieve 1-2 m/s precision in the visible and 5-10 m/s precision in the near-IR; further improvements are expected from ongoing work on temperature control, calibration procedures and data reduction. Comparing the RV precision achieved in different wavelength bands, we find a ¿sweet spot¿ between 0.7 and 0.8¿m, where deep TiO bands provide rich RV information in mid-M dwarfs. This is in contrast to our pre-survey models, which predicted comparatively better performance in the near-IR around 1¿m, and explains in part why our near-IR RVs do not reach the same precision level as those taken with the visible spectrograph. We are now conducting a large survey of 340 nearby M dwarfs (with an average distance of only 12pc), with the goal of finding terrestrial planets in their habitable zones. We have detected the signatures of several previously known or suspected planets and also discovered several new planets. We find that the radial velocity periodograms of many M dwarfs show several significant peaks. The development of robust methods to distinguish planet signatures from activity-induced radial velocity jitter is therefore among our priorities. Due to its large wavelength coverage, the CARMENES survey is generating a unique data set for studies of M star atmospheres, rotation, and activity. The spectra cover important diagnostic lines for activity (H alpha, Na I D1 and D2, and the Ca II infrared triplet), as well as FeH lines, from which the magnetic field can be inferred. Correlating the time series of these features with each other, and with wavelength-dependent radial velocities, provides excellent handles for the discrimination between planetary companions and stellar radial velocity jitter. These data are also generating new insight into the physical properties of M dwarf atmospheres, and the impact of activity and flares on the habitability of M star planets. © 2018 SPIE., CARMENES is an instrument for the Centro Astronomico Hispano-Aleman de Calar Alto (CAHA, Almeria, Spain).

Many organizations are carrying out recruitment process by using social media networking sites. Social networking sites are used to facilitate and improve process of recruitment method in HR management. Social networking sites address the needs of employers and job-seekers via internetworking on electronic platform likes face book, twitter, LinkedIn, naukri.com, and monster.com which increase the speed of employment, reducing the cost of recruitment, huge availability of jobseekers and improve the quality of recruitment and services. In this paper it describes awareness about the recruitment through social media. Social Media in recruiting process is a win-win for both company and potential candidates. The paper concludes with instead of relying heavily on external recruitment firms or job boards, many companies are focusing on locating specialized talent through Social Media sites such as LinkedIn. This paper will focus on the most popular social media platforms: LinkedIn, Face book, Twitter and other platforms like Naukri.com, Monster.com.

Quality of work life has become one of the essential concerns among contemporary corporate employees and employers. The purpose of this study is to evaluate the quality of work life among the commercial bank employees and the various factors influencing the quality of work life.. Stratified sampling technique is employed in the study with a sample size of 596 from the population of 2008 in the five taluks of Erode District, constituting the employees working in the branches of both the private and public banks. The data were analyzed with the help of statistical tools such as percentage analysis, two way tables, Chi-square Test, Univariate tools, regression analysis, factor analysis and structural equation modelling and Henry Garat ranking. It could be noted from the study findings on private sector commercial bank employees they felt good quality of work life than the public sector employees. Public sector management should gratify their employees by offering equivalent facilities to augment their quality of work life which leads to increase in work commitment among the employees in banks in the study area. Transforming the workplace proactively using a combination of well designed quality of work life initiatives for their employees will yield competitive advantage as it will increase employee job satisfaction. This in turn will motivate the employees to perform in superior way, leading the commercial banks to a better future by yielding the expected outcome.
