An integrated Hardware/Software Verification and Validation methodology for Signal Processing Systems

The testing and validation services team assesses project deliverables at various stages of development using innovative and effective verification and validation, to ensure that the deliverables are compliance with the customer specifications and requirements. Whenever new products and devices are released, completely integrated verification and validation services are delivered to accurate and complete records usability, performance, and quality assurance services. Throughout the product development and testing process, the testing and validation services team employs verification and validation techniques. Code reviews, walk through, inspections, desk-checking, and code execution are all examples of verification and validation techniques. Services for verification and validation are used to assess whether or not the software or application provided complies with the requirements and serves the intended purpose. A procedure used to ensure that the software created is of good quality and consistently operates as expected is independent testing and validation services. Unit testing (also known as “White Box Testing”), hardware-software integration testing (HSIT), and system testing are the three primary independent verification and validation approaches (Black Box Testing). The teams responsible for the verification and validation services actively participate in each stage of the project and design the services according to the project’s needs (e.g., prototype, spiral, iterative, V Model, and Agile). Our expertise in the embedded domain, tried-and-true verification and validation techniques, and a thorough methodology provide a quick turnaround and excellent results for the targeted solution.

Patients’ impact on the hidden curriculum of medical students a qualitative study on undergraduate medical students

Aim: To explore and understand professional practice development through medical students’ observation of patient’s responses towards the medical students, illness, and hospital staff. Methodology: Semi-structured focused group discussions were conducted between 3rd September 2019 and 3rd May 2020 using non-probability purposive sampling. Three focused groups were conducted with fourth year medical students (n=19) to discuss about their third-year clinical placement experience. The focused group discussions were audio-recorded and transcribed verbatim. Data were analysed using Interpretative Phenomenological Analysis framework to label the concepts, attached code to the data, and the codes were subsequently grouped into similar themes. Themes that emerged from the interpretation of the coded data were identified. Results: Four main themes emerged from the focus groups: (1) Student’s observation on patient’s responses towards students, illness, and staff; (2) Patient’s perspectives towards students; (3) Students were affected by the experience; and (4) Factors influencing patient’s responses to students, illness, and staff. The impact of patient’s behaviour has influenced students’ professional practice in two ways. The first impact is collaboration of students’ observation during clinical placement with what has been learned through the written curriculum. The second impact is through a hidden curriculum. Conclusions: The hidden curriculum has influenced our students’ learning through observation of new aspects and implementation of the learned written curriculum. Students can aspire medical educators, doctors, and medical staff to adopt approaches and attitudes that have a positive impact on students’ professional practice and to acknowledge that they are the role models for the new generation’s learning through the hidden curriculum

Theoretical Analysis of Continuous Heat Extraction from Absorber of Solar Still for Improving the Productivity

This paper communicates the theoretical analysis of continuous waste heat extraction from the other side of absorber plate. For theoretical analysis two conditions are determined one is the mass of water in the absorber and another one is mass flow rate of water around the absorber plate. Results indicated that the water temperature is reached maximum at 10 kg of mass and 5 kg/hr mass flow of water and the heat extracted from the absorber is higher at optimum mass flow of 5 kg/hr. Also, the higher temperature difference between the water and the collector cover is found during the off-shine period. The maximum achievable hourly productivity of 0.9 and 0.5 kg is found for the solar still with and without circulation respectively. The yield from present model with continuous heat extraction is increased from 3 to 5.5 kg/m2. As the approached method is more new to the society it may be determined by Agouz- Nagarajan- Sathyamurthy (ANS) model

Experimental Evaluation of Solar-Powered Desalination Ponds in Waste Water Treatment

The purpose of this research is to examine a desalination pond that is experimental in size and uses solar energy for its heating. The solar pond is the major components of a zero discharge desalinate progression (ZDDP), as shown below. The projected ZDDP may treat the sewage waste water produced by the petrochemical complex's purification unit, resulting in the productivity of both fresh water and salt. The solar desalination pond that was researched and utilized the evaporation distillation process. A solar desalination pond's primary function is that of a batch stage. The experiment results are presented after an introduction of the solar powered desalinate pond and the distillation procedure. The results prove that the proposed solar-powered pond can be realistically executed. The proposed solar-powered pond to a standard solar-powered pond in terms of the rate at which it gains distilled water were compared

Comparative study of tubular solar stills with phase change material and nano-enhanced phase change mMaterial

This study is intended to investigate and analyze the operational performances of the Conventional Tubular Solar Still (CTSS), Tubular Solar Still with Phase Change Material (TSS-PCM) and Tubular Solar Still with Nano Phase Change Material (TSS-NPCM). Paraffin wax and graphene plusparaffin wax were used in the CTSS to obtain the modified solar still models. The experimental study was carried out in the three stills to observe the operational parameters at a water depth of 1 cm. The experiment revealed that TSS-NPCM showed the best performance and the highest yield in comparison to other stills. The distillate yield from the CTSS, TSS-PCM and TSS-NPCM was noted to be 4.3, 6.0 and 7.9 kg, respectively, the daily energy efficiency of the stills was observed to be 31%, 46% and 59%, respectively, and the daily exergy efficiency of the stills was recorded to be 1.67%, 2.20% and 3.75%, respectively. As the performance of the TSS-NPCM was enhanced, the cost of freshwater yield obtained was also low in contrast to the other two types of stills

A Template-Based Java Code Generator for OpenModelica and MetaModelica

The current OpenModelica Complier (OMC) translates Modelica models into executable Ccodethrough several stages. The Code Generator is the final stage of the compiler whichgenerates target C-code from the optimized sorted equations. Recently, the Code Generator inOMC has been rewritten using the OpenModelica text template language. This gives a moreconcise and easier to understand code generator. Modeling and simulation is becomingincreasingly used in several application areas. There is demand for the OpenModelicaComplier (OMC) to generate code in languages like C#, CSharp, XML, JAVA and so on. Inthis thesis work, we implement a Java code generator to translate the internal equation-basedmodels in OpenModelica and its extension MetaModelica into a Java code representation. Tocreate the Java code generator we used the OpenModelica text template language, also calledSusan. This work is an important step on the way to finalize a full version of a Java CodeGenerator for the OpenModelica Complier (OMC)
