A systematic review on the therapeutic lighting design for the elderly

Research suggests that specialized lighting design is essential to cater for the elderly users of a building because of the physiological changes in the eye with increased age. Recent studies have established that lighting in a space impacts on users’ physical performance as well as on the mental state. In particular, light therapies have been found to be successful in treating several mood disorders in the elderly. Nevertheless, information relating to the therapeutic performance of lighting is scattered and comparatively less studied in built environment research. This review aims to identify the criteria for the therapeutic lighting design for the elderly and to discuss its applicability on contemporary design practices. Methodologies adopted for this study include a systematic review of literature to synthesize recent research findings and an evaluation of lighting guides published by the regulatory bodies and professional institutions to identify current practice. The review identified that there are substantial amount of evidence exists, which can be incorporated during elderly lighting design to increase the therapeutic performance of the space. Apart from enabling the users to navigate safely and perform routine tasks, the therapeutic performance of lighting is significant to enhance elderly wellbeing. Depression, delirium, sleep disorder and disorder in the circadian system are common mood disorders among the elderly, which are evidently influenced by the lighting environment. Advancements in lighting technology, in particular in low energy Light Emitting Diode (LED) lighting have led to new approaches to meet detail photometric parameters to construct the desired therapeutic environment. Our understanding of the photo-biological effects of lighting has enhanced, however the evidence is not well integrated with design guidelines. The research reported here has made an attempt to bridge this gap by developing a comprehensive knowledge base of the therapeutic lighting design for the elderly

Evaluation of four artificial lighting simulation tools with virtual building reference

There are number of software environments available to conduct lighting simulation to support researchers and designers. This paper compares and analyses performance of four lighting simulation programs, they are, AGI32, DIALux, RADIANCE and RELux. Along with the evaluation of modelling ability and output features, two significant aspects of lighting calculation focussed in this study are accuracy in calculating illumination level and luminaire number for interior spaces. Illumination level calculation is validated by Commission International de Eclairage (CIE) recommended methodology known as CIE test cases. Another virtual space is used to evaluate luminaire number calculation capability. Modelling and simulation were conducted by all four packages. Validation was done by comparing simulation results with analytical and manual method calculation

Optimize task distribution in grid computing

This thesis report is submitted in partial fulfillment of the requirements for the degree of Bachelor of Science in Computer Science and Engineering, 2008.Cataloged from PDF version of thesis report.Includes bibliographical references (page 73).Grid computing is designed to use free cycles of computer to perform large calculations by using free cycles of computer. Grid computing does not need dedicated computers to perform calculations instead it uses free cycles of computer in a network. It works like a virtual super computer, but it doesn’t involve extra hardware cost. As, it’s a cost effective its popularity is increasing day by day. Now a day’s popular applications are being made to support grid computing. For example Oracle database 10g is designed to support grid computing. Although grid computing is so popular, but implementing software for grid based system is tough. It needs task distribution among computers. So it uses different programming techniques and needs to use special API. The software we are currently using may not support grid environment. Software companies need to convert their programs to support grid environment that involves development cost. On other hand users are not able to use their current software in grid environment. So, they need to buy another program that involves extra cost. The objective of this project is to run traditional programs in grid system without any modification, so that we can run any executable program in grid system with parallel speeding performance. It will increase program compatibility and reduce cost.Shyen Muhabbat ShikderB. Computer Science and Engineerin

Heterosis analysis in strain-crossed hybrid Rohu (Labeo Rohita) through mMicrosatellite DNA variability assay

Labeo rohita is an important commercial aquaculture species in Bangladesh, but it needs improved growth performance to meet the increasing demand for fish. Genetic improvement through inter-strain crossing, generating heterosis, is quicker than a selection strategy. Therefore, crosses were made between two strains of rohu: Padma River strain and a hatchery strain. Growth performance analyis showed the highest growth rate in the Padma × Padma cross followed by one of the reciprocal crosses Hatchery♂ × Padma♀ (hybrid). The lowest growth rate was observed in Hatchery × Hatchery cross. DNA variability study using three microsatellite markers showed polymorphism (P95) in these crosses. Variations were observed in number and frequencies of alleles and mean heterozygosity in different loci; the mean number of alleles varied from 4.667±0.882, 3.333±1.333 and 2.667±1.202 in Padma, hybrid and Hatchery strains respectively. Relatively high levels of gene flow and low Strain differentiation (FST) values were found between the Padma and hybrid strains. The UPGMA dendrogram based on genetic distance placed the Padma population in one cluster and the hybrid and Hatchery populations in another. The results revealed that there was relatively low level of genetic variability in the riverine and hatchery reared populations of L. rohita in Bangladesh

Efficacy and Safety of Intrathecal Morphine For Post Cesarean Analgesia Under Spinal Anesthesia

Background: Cesarean section is the most common operation in obstetrics. It is also a well-known fact that mother has to bear severe post-operative pain because of unavailability of better analgesic and modern techniques of pain control at all the centre and that too free of cost, in the current era of cost containment. Objective: To evaluate the efficacy and safety of intrathecal morphine for post cesarean analgesia under spinal anesthesia. Methods: This prospective, randomized, case-control study was conducted in Department of Anaesthesiology, Gonoshasthaya Samaj Vittik Medical College, Savar, Dhaka, Bangladesh from January to June 2022. A total of 150 parturients posted for Cesarean section under spinal anesthesia were divided into two groups of 75 each in this prospective randomized case-control study. Morphine group received 0.15 mg of intrathecal morphine mixed in 12 mg of 0.5% bupivacaine heavy while control group received 12 mg of 0.5% bupivacaine heavy alone, after proper preparation of spinal anesthesia. The parturients were assessed for first request of analgesic as per Visual Analog Scale, frequency of analgesics required within 24hr, nausea, vomiting, pruritus, sedation and respiratory depression. Results: Postoperative analgesia was significantly greater in morphine group as compare to control group (12.1±7.6 vs 3.7±2.9hr). Frequency of analgesics requirements was also significantly lower in morphine group (1.7±2.0 vs 3.4±8.1). Visual Analog Scale was below 4 at most of time in morphine group. The incidence of nausea, vomiting and pruritus were more in morphine group as compare to control group but without any respiratory depression. There was no significant difference in APGAR score among fetus. Conclusion: Mixing low dose of intrathecal morphine in standard dose of spinal anesthesia effectively prolongs the duration of post cesarean analgesia and decreases the frequency of analgesics requirement without any major complication in parturients or fetus.       &nbsp

Most of respondents 70.10% had medium level of adoption towards catfish farming while 15.46% and 14.44% of them had low and high level of adoption respectively. Among the influential variables, education, farming experience, attitude towards catfish culture, problems faced by the farmer during adoption of catfish farming were significant contributor. Most of the farmer of the study area culture Pangas, Shing, Pabda , Tengra and Magur. Adoption of catfish cultivation is increasing in the study area. High price of material inputs, diseases outbreak, broker problem, inbreeding in fish, unavailability of skilled manpower, flood or heavy raining, poor transportation systems were found constraints among farmers during catfish farming. For sustaining and enhancing catfish cultivation, farmers’ need to provide with reasonable price of material input, need to provide natural and pure catfish breeder species, need government’s continuous support, develop transportation system, ensure adequate training to create skill manpower. Key words: Adoption, Catfish Farming, Innovation, Jashor

Interactive constraint-based space layout planning

Layout planning is the primordial design activity that determines the characteristics and performance of a building throughout its lifecycle. Due to its iterative nature, there is a growing interest in the automation of space layout planning to enhance the search for optimum design solutions. The approaches for automation range from constraint/heuristics-based to the application of numerical optimisation algorithms. Among these, the use of design constraints to guide the search of the solution space is well regarded due to its ability to model design problems of an applied nature with multiple objectives. Constraint-based approaches also allow interactivity between the designer and layout planning process, which simulates the iterative nature of creative design and can be integrated well with the existing design process. Interactivity also enhances the management of design knowledge through improved processing and visualisation of information. This paper presents a theoretical framework for interactive constraint-based layout optimisation with an implemented prototype for a hospital patient room interior layout. The theoretical framework was developed by analysing existing layout automation methods and interactive approaches through a review of relevant literature. Object-oriented computer programming was used to develop the prototype to demonstrate the proposed approach of interactive layout planning system. The framework augments the iterative design process by facilitating the active participation and sharing of the designer’s knowledge during the aggregation. With regard to the implementation of the framework in large problems, fast evaluation of design solution was found to be necessary to interact with the system in real time. Interactive constraint-based layout optimisation has, therefore, the ability to enhance the search process of optimum design solutions by augmenting the iterative nature of the creative design process

Advance Temperature Modeling of Solar PV

Advance Temperature Modeling of Solar PV Md Abdul Adud Shikder The low electrical efficiency of the mono-crystalline silicon photovoltaic module is a major drawback that reduces the competitiveness of solar photovoltaic power generation. The purpose of this thesis is to determine the improved efficiency by cooling of the mono-crystalline solar photovoltaic module with the prevailing winds in rural areas. The effect of the prevailing winds was determined by measuring the temperature of the mono-crystalline solar photovoltaic module using an advanced thermal model of the flat plate collector. The surface azimuth of the module is adjusted to minimize the angle between the prevailing wind and module surface to obtain optimum cooling for maximum output power. An analytical relationship between wind speed, wind direction, and panel surface azimuth is developed to achieve maximum output. It is observed in the thermal model that for a wind speed variance of 4 m/s, the efficiency of mono-crystalline silicon solar module increased by 22.9%. Experiments had been carried out in the Concordia solar simulator laboratory where 2.2% variation were found between calculated and experiment results for output power and efficiency. The experiment also validated the temperature variation in different solar cells within the module, which causes a loss in open circuit voltage and output power
