Apple is one of the most popular fruits due to its dietary composition and the presence of biologically active compounds that have positive impacts on human health. This is the reason it is cultivated extensively worldwide. To preserve food items drying is one of the oldest techniques. The dried apples can be stored for a longer duration and are used as packaged snacks. Fruits can be dried rapidly with the help of microwave drying technique and hence it is used by industries to dry food items at a commercial scale. In this research paper, the microwave drying technique is applied to an apple in a COMSOL Multiphysics simulator. Then the results are observed to know at what temperature and for how much time apple should be dried so that its nutrients remain preserved.

Quantum-dot cellular automata (QCA) is one of the applicable alternatives to current CMOS because of static hazards, leakage current and smaller area requirement. Therefore, it has achieved an important place in a digital circuit. In this work, the design of an efficient 2:1 demultiplexer structure based on a 3-input majority gate is proposed. This DEMUX design outperforms the existing 2:1 DEMUX designs available in the literature in terms of effective area, cell count and delay. The proposed demultiplexer design has 0.25% less effective area, 21 number of QCA cells with the delay of 1 clock cycle.

In this paper a compact wideband Filtenna structure with stopband characteristics has been presented. The proposed filtenna is a planar elliptical patch with a CSRR structure embedded in the partial ground. The elliptical shape is utilized to attain the wideband characteristics whereas the CSRR is etched out to filter out the undesired bands. This filtenna design exhibits an impedance bandwidth of 3.3 GHz ranging from 2.47 GHz to 5.77 GHz covering the WLAN (2.4/5.2 GHz) and WiMAX (2.5/ 3.5/ 5.5 GHz) bands and effectively rejects the higher bands beyond 5.77 GHz. The designed filtenna achieves a maximum gain of 4.11 dBi and a bidirectional radiation pattern over the desired bandwidth. The overall dimensions of the proposed filtenna is 40 mm x 50 mm x 1.6 mm with the patch area 14 mm x 10 mm. The proposed filtenna is designed, simulated and optimized using CST Microwave Studio and has been fabricated and tested to validate the proposed design.

Internet of things (IoT) has provided a technological platform for purposeful connectivity. IoT allows smart devices and sensors to sense, connect and control the devices even remotely. The development in the field of Internet of Things has been enormous and the application of these solutions is scalable to high limits. The quantum of Internet of Things (IoT) is developing fast and is predicted to reach each and every sector of the computing world. We are already converging towards smart homes, smart highways, and smart cities. The defense sector of any nation is also affected by these developments. Defense field's solution is primarily based on sensors and their deployments. The primary aim of sensory data is the conclusion of information suitable for tactical decision and analysis in the Future battlefield environment. From capturing soldier's vital health parameters to its weapons, ammunition, location status, every data has a purposeful meaning and is of particular importance to the tactical commander sitting in the command center. We are proposing a novel mechanism to combine Internet of Things with the emerging graph database for better decision support system so as to create a situational awareness about every parameter of the soldiers in the battlefield. We present a simulated use case scenario of the future battlefield to query the graph database for situational awareness pattern for tactical advantage over the opponents.

An idea or a concept can be classified as transformational, operational or tactical. In the recent past, there have been more rational developments in software testing techniques outsmarting the ones prevailing earlier which weighed more in favor of empirical rather than logical aspects of software testing. This paper presents one of a kind of developments in software testing methodologies that were motivated by Operations Research modeling and describes in considerable detail the applicability of one of these models with regard to (w.r.t.) the application of available resources for optimizing the software quality metrics while adhering to the release schedule as well. The paper introduces a new and pioneering concept what we call Intelligent Software Testing (IST) technique which is not only transformational but operational and tactical as well. It examines areas and opportunities and utilizes them to make informed decisions w.r.t. the allocation of tasks where systems involving software testing can be improved, from design to delivery. The IST proposed herein undertakes two-way optimization w.r.t. competence and efficiency. It not only promises but delivers highest standard of software quality level by maximizing team competence and commitment to keep a date with the release schedule by minimizing activity time, both being crucial to software testing phenomenon.
