Enhancing thermal comfort and indoor air quality through energy optimization with neural network

Indoor thermal comfort and air quality are essential for occupant well-being, while simultaneously optimizing energy consumption in buildings. Achieving a balance between these factors presents a significant challenge, as indoor environments are dynamic and energy demands fluctuate. By modifying ventilation rates in response to real-time data, demand-controlled ventilation systems can reduce energy consumption and enhance indoor comfort and air quality. However, optimizing these systems with advanced predictive models remains a complex task. To address this challenge, this publication proposes a Dual-Stream Multi-Dependency Graph Neural Network (DMGNN)-based energy-efficient ventilation management technique that maximizes indoor air quality and thermal comfort. The suggested method seeks to enhance thermal comfort and air quality by maximizing heating, ventilation, and air conditioning (HVAC) operations while reducing energy consumption. Initially data are collected from an Indoor Air Quality Monitoring Dataset. The DMGNN is employed to capture the complex dependencies between environmental factors such as temperature, humidity, and CO2 concentrations, considering both temporal and spatial relationships. Implementing the proposed system and evaluating it through simulations in various building environments demonstrates notable improvements in thermal comfort, indoor air quality, and energy economy. The suggested system’s performance is contrasted with that of other current methods, showing superior energy efficiency and optimization of both indoor air quality and occupant comfort. This study presents an innovative, scalable framework for smart building management, promoting sustainable energy solutions.

Tracking students' progress in introductory c programming courses through moodle tests with randomized questions

Assessing students' progress in introductory programming courses is crucial for identifying learning gaps and improving teaching methods. This study evaluates the effectiveness of Moodle-based tests with randomized questions in monitoring student progress in C programming courses at J. Selye University during the 2023/24 academic year. A series of ten tests were administered across two courses, covering essential programming topics such as data types, variables, conditional statements, loops, two-and three-dimensional arrays, recursion, and sorting algorithms. The results revealed significant variations in student performance, with recursion and the pretest/posttest loops presenting the greatest challenges. The correlation analysis of test scores showed strong relationships among related topics, confirming the structured progression of the curriculum. These findings suggest that Moodle-based assessments offer valuable insights into students' learning trajectories, enabling educators to adapt their instructional strategies accordingly. Such insights can help optimize introductory programming curricula, enhancing student engagement and understanding.

Improving the performance of double-expansion chamber muffler using dielectric beads; optimization using factorial design

Purpose Noise pollution is a common health hazard worldwide which is emitted along with chemical air pollutants, simultaneously from many sources. Some studies have been conducted to control these pollutants, simultaneously with promising results being achieved. Dielectric beads have been used in air pollution control technologies, successfully and probable effectiveness of them in noise reduction can be promising in dual use of them in the exhausts emitting noise and air pollution, simultaneously. Methods In order to investigate the effectiveness of dielectric beads in noise reduction, two types of them; namely glass and ceramic beads, were placed separately inside the connecting tube of a double-expansion chamber muffler. Then the transmission loss (TL) of muffler was examined using impedance tube. A factorial design was used to evaluate and optimize the effect of noise related parameters on TL of such a system. Results Results show that the presence of dielectric beads has significant effect on TL of muffler. The maximum TL was obtained as 74.76 dB for muffler with ceramic beads, under the optimal condition of 5250 Hz and 120 dB. Measurement of TL and sound absorption coefficient (SAC) of glass and ceramic beads showed that the noise reduction in muffler with ceramic and glass beads is probably due to SAC in ceramic beads and noise reflections in glass beads, respectively. Conclusion These results promise the dual use of dielectric beads in the exhausts emitting noise and air pollution simultaneously.

Post-marketing quality assessment of paracetamol brands in the libyan market

Paracetamol is one of the most found over the counter drugs worldwide. It is widely used as an analgesic and antipyretic drug. Many commercial types of paracetamol tablets are available under different brand names in the Libyan drug market. The present study was conducted to evaluate post-marketing quality parameters for three brands of paracetamol tablets marketed in Libya. All three brands were evaluated for weight variation, hardness, friability, disintegration time and uniformity of content following British pharmacopeia guidelines. The outcomes of this study showed all tested brands complied with the British pharmacopeia specifications for the weight variation test, friability test (0.05%-0.17%), and hardness test (171.3N-197.6 N). In addition, two brands passed the British pharmacopeia requirements for the disintegration time test, whereas one brand exceeded the allowed disintegration time by about five minutes. Furthermore, high performance liquid chromatography was used to determine paracetamol content. Although the average amount of paracetamol drug available in these brands is not very close to 100%, where one brand achieved the lowest value (438.1 mg), the loaded dose of paracetamol in selected tablets in the three brands was within the British pharmacopeia standard specifications for the uniformity content test. Therefore, it can be concluded that almost all the three tested brands of paracetamol tablets that are available in the Libyan drug market meet the British pharmacopeia specification for quality control analysis.

Development of Human Resources is being given due importance by all the organizations as it aims at developing all the employees of an organization in a planned manner to acquire, sharpen and apply their existing capabilities as well as their inner potentials. HRD is a total system in which its various mechanisms are embedded together to act as an integrated unit. No sub-system can work in isolation. The researches show that the working of each sub-system has its impact on other subsystems e.g. Performance appraisal is basis for assessing training needs, career planning etc. Training is useful tool for increasing individual efciency. It is also a part of employee welfare and is used for promotions. Implementing these HRD sub-systems helps in developing a climate in the organization where the people collaborate with each other; respect and trust others and work as a team. This, in turn, develops a highly positive and motivated workforce which enables the organization to achieve its goals. Human being is a creature composed of heredity and environment and creates values for their own. In the context, during the interactions with others, the values manifest spontaneously. Human beings are tempted by all kinds of emotions, impulses, instincts, prejudices, wishful thinking, hopes, fears, desires, and almost everything.

Using common medicinal plants to treat high blood pressure: an updated overview and emphasis on antihypertensive phytochemicals

The primary cause of many fatalities is hypertension (high blood pressure). Many hypertensive patients are not even aware that they have the condition. As a result, hypertension is sometimes referred to as a silent killer. Until the harmful effects of high blood pressure, such as myocardial infarction, stroke, renal abnormalities, and vision problems, are identified, hypertension is typically asymptomatic. Without the use of herbs and dietary control, conventional medication therapy could not be enough to treat hypertension. The growing number of persons with high blood pressure can be effectively treated using alternative medicine. Numerous alternative therapies, such as diet, exercise, stress management, vitamins, and herbs, have been proven to be effective in lowering high blood pressure. There are several medications available to treat this disorder however popular antihypertensive medications typically have a long list of adverse effects. Numerous active ingredients with pharmacological and preventative qualities found in medicinal plants can be used to treat hypertension. This review discusses an overview of important medicinal plants and phytochemicals with hypotensive or antihypertensive effects.

Liposomes for drug delivery - liposomes

Liposomes are a novel drug delivery system (NDDS), they are vesicular structures consisting of bilalyers which form spontaneously when phospholipids are dispersed in water. They are microscopic vesicles in which an aqueous volume is entirely enclosed by a membrane composed of lipid bilayers. NDDS aims to deliver the drug at a rate directed by the needs of the body during the period of treatment and direct the place of action. Liposomes are colloidal spheres of cholesterol non-toxic surfactants, sphingolipids, glycolipids, long chain fatty acids and even membrane proteins and drug molecules or it is also called vesicular system. It differs in size, composition and charge and drug carrier loaded with variety of molecules such as small drug molecules, proteins, nucleotides or plasmids etc. Few drugs are formulated as liposomes to improve their therapeutic index.

Pdf - attention is all you need

The dominant sequence transduction models are based on complex recurrent or convolutional neural networks that include an encoder and a decoder. The best performing models also connect the encoder and decoder through an attention mechanism. We propose a new simple network architecture, the Transformer, based solely on attention mechanisms, dispensing with recurrence and convolutions entirely. Experiments on two machine translation tasks show these models to be superior in quality while being more parallelizable and requiring significantly less time to train. Our model achieves 28.4 BLEU on the WMT 2014 Englishto-German translation task, improving over the existing best results, including ensembles, by over 2 BLEU. On the WMT 2014 English-to-French translation task, our model establishes a new single-model state-of-the-art BLEU score of 41.0 after training for 3.5 days on eight GPUs, a small fraction of the training costs of the best models from the literature.

Design and analysis of a scooping engine valve

Inlet valve in an engine tends to be subjected to immense thermal loads besides chemical corrosion. Opening and closing of inlet valve practically could be in the order of 2000 times per 1.6 km. In the mean time of engine working cycle, seat insert of the inlet valve is the surface, against which an intake valve seats. Conventional engine valves are provided with a curved angle for its seating position, but for this study, the same is proposed to be positioned at a tapered angle. This tapered position as converted into radius in order to permit rich air at the inlet and reduce exhaust emission. This study is to investigate the nature of the future redesigned Scooping valve for a 1.25L 4-cylinder Petrol engine with VTVT (Variable Timing and Valve Train) under combined mechanical and thermal loading cycle by feeding the input conditions for this study after NX-CAD modelling in ANSYS 10.0 software and the numerical results thus obtained are recorded for future valve design considerations.

Pharmacognostic and preliminary phytochemical investigation of aerial parts of centella asiatica linn

In the Indo-Pak subcontinent, the traditional systems of medicine, both Ayurvedic and Unani, are primarily based on herbs and herb-based preparation for therapy. Therefore, the importance of the herbal identification process remains critical in achieving the desired and successful therapeutic effect. To support the manufacturers and practitioners of both systems, many herbs are still collected from wild sources, as herbal farming is not very developed in this part of the world. During a survey program conducted in different areas of Pakistan, significant lacks and gaps were noted to be present in the identification & characterization of herbs, which needs to be addressed and fulfilled as many species look alike apparently or physically but have different biological or pharmacological activity. Based on this objective and approach, Centella asiatica was selected for the pharmacognostic and preliminary phytochemical investigation to establish a better correlation and to provide useful methods in its identification as the use of Centella asiatica is very common in Pakistan and other South Asian countries for CNS disorders therapy. Therefore, this study aimed to develop & report some and rapid identification methods for Centella asiatica. The present study includes physical, physicochemical, preliminary phytochemical and fluorescence analysis. For the first time, in the present study, NIR and FT-IR spectra of Centella asiatica have been reported for identification. The findings of the present study are quite promising and can be helpful for the manufacturers and researchers in the identification and development of Centella asiatica-based new drugs or formulations.

Hypotensive activity of melilotus officinalis (l.) pallas

Melilotus officinalis (L.) Pallas. is used traditionally to treat hypertension and chronic venous insufficiency. The high prevalence of hypertension and the side effects of antihypertensive drugs potentiate us to evaluate Melilotus officinalis. The hypotensive effect of Melilotus officinalis butanol fraction (MOBF) was investigated in anaesthetised normotensive rats. The doses of 60, 80 and 100 mg/ kg, i.v., produced a significant (P<0.05) decrease in blood pressure. The statistically non-significant reduction in blood pressure was shown by 20 and 40 mg/ kg, i.v. These results suggest that Melilotus officinalis exhibited a hypotensive effect in normotensive rats. However, further evaluation of compound-related activity is required.
