    Computers are the pervasive technology of our time. As computer become critically tied to human life, it also becomes more important that interactions with them are under control. They are no longer a novelty, but are integrated into the fabric of our world, performing both high and low-level tasks. That is, computers may be used to eliminate heavy, redundant work and more. Sophisticated machines have been deployed to perform remote surgery or detect subterranean landmines in repopulated civilian areas. The increasing importance of computers in our lives means that it is essential that the design of computer systems incorporates techniques that can ensure reliability, safety and security. This paper will examine technological mishaps involving the use of computers. This review will include notorious software bugs that have affected finance, communication, transit, defense, health and medicine and others systems or industries. The sequence and etiology of these accidents will be discusses as well as how catastrophes may be avoided in the future through lessons and practices based on research

    Wireless Multichannel Multipoint Broadcast Service for Mobile Stations

    Get PDF
    In wireless Multicast Broadcast Service (MBS), the common channel is used to multicast the MBS content to the Mobile Stations (MSs) on the MBS calls within the coverage area of a Base Station (BS), which causes interference to the dedicated channels serving the traditional calls, and degrades the system capacity. The MBS zone technology is proposed in Mobile Communications Network (MCN) standards to improve system capacity and reduce the handoff delay for the wireless MBS calls. In the MBS zone technology, a group of BSs form an MBS zone, where the macro diversity is applied in the MS, the BSs synchronize to transmit the MBS content on the same common channel, interference caused by the common channel is reduced, and the MBS MSs need not perform handoff while moving between the BSs in the same MBS zone. However, when there is no MBS MS in a BS with the MBS zone technology, the transmission on the common channel wastes the bandwidth of the BS. It is an important issue to determine the condition for the MBS Controller (MBSC) to enable the MBS zone technology by considering the Quality of Services (QoS) for traditional calls and MBS calls are used to reduce the dependency over the common channel and also it is going to reduce the delay over the network. By enabling Dynamic Channel Allocation (DCA) and Enhance Dynamic Channel Allocation (EDCA) we are going to overcome these problems

    Factors influencing implementation of mass drug administration for lymphatic filariasis elimination: a mixed-method study in Odisha, India

    Background: Lymphatic filariasis (LF) persists as a public health problem in India. Despite more than ten rounds of mass drug administration (MDA), LF continues to be endemic in the Dhenkanal district of Odisha. Hence, we assessed the coverage and compliance of the MDA program and explored the factors affecting it in the Dhenkanal district.Methods: An explanatory mixed-method study was conducted, wherein for the quantitative survey, 552 participants aged 2 years and above were recruited following a multistage cluster random sampling during February 2022. In-depth interviews were conducted among purposively selected key stakeholders and program implementers. Descriptive statistics were used to report coverage and compliance, along with a 95% confidence interval. Qualitative data were analyzed using a thematic approach.Results: We observed coverage of 99.28% and compliance of 85.87% for MDA drugs. Supervised drug administration proved to be a major pillar in increasing compliance. There was difficulty in administering drugs in urban areas due to gated societies, the absence of individuals during the day, and the perspective toward healthcare providers. Participants reported a lack of confidence in drug distributors and a fear of side effects as major causes for non-compliance.Conclusion: There is a need to strengthen MDA, especially in urban areas. An urban-specific strategy, along with surveillance, behavioral change communication, and the involvement of multi-disciplinary teams, is required

    Educational Aspirations as The Predictors of Teacher Engagement in Classroom in Context of Emotional Intelligence of Teachers

    Get PDF
    In the intricate network of factors that influence teacher engagement within the classroom, educational aspirations stand as potential critical predictors. These aspirations, which could be defined as the goals and objectives set by educational institutions or by the teachers themselves, could serve as a guiding force, steering the level and quality of engagement teachers display in the class. This essay explores the hypothesis that educational aspirations could indeed be potent predictors of teacher engagement, delineating the pathways through which aspirations mold teachers' dedication, enthusiasm, and proactive involvement in the educational process. Initially, it is fundamental to understand that educational aspirations are a two-pronged entity - encompassing the macro-level aspirations set forth by educational boards and policies, and the micro-level aspirations nurtured by individual teachers for their personal growth and the academic progression of their students. These aspirations, when clearly articulated and aligned, can act as a catalyst, propelling teachers towards higher levels of engagement in class. From one perspective, aspirations can foster engagement by instilling a sense of purpose and direction. When teachers are driven by well-defined goals - be it enhancing student literacy levels, fostering critical thinking skills, or nurturing holistic development - their engagement in class is naturally heightened. They are more likely to invest time and effort in devising innovative teaching strategies, engaging in continuous learning, and fostering an environment that is conducive to achieving these aspirations. Furthermore, educational aspirations often encapsulate the ideals of inclusive and equitable education. Teachers working towards these aspirations are likely to be more engaged, as they strive to create classrooms where every student is given an opportunity to thrive. This inclusive approach not only fosters positive student outcomes but also enriches the teacher's experience, as they find fulfillment and satisfaction in witnessing the growth and development of their students. Moreover, educational aspirations can foster a collaborative spirit among teachers. As they work towards common goals, there is an enhanced sense of community and collaboration

    Influence of Al Content on the Corrosion Behavior of Biodegradable Magnesium Alloys in Simulated Physiological Solution

    Magnesium (Mg) and its alloys have gained wide popularity in the biomedical field as promising candidates for degradable implant applications. Among Mg alloys, AZ (aluminum and zinc) series alloys are the most widely investigated for implant applications and reported in the literature. In all AZ series Mg alloys, aluminium content is the influencing factor that imparts different properties to the Mg alloys. In the present study, pure Mg, AZ31 and AZ91 Mg alloys were selected and the effect of aluminium content on the biocorrosion has been investigated in Ringer’s solution. It was a clear observation that the increased aluminum content has a severe effect on the degradation behavior of magnesium. From the weight loss measurements, AZ31 has shown lower corrosion rate compared with pure Mg and AZ91. The surface morphologies also showed the formation of more pits on pure Mg and AZ91 Mg alloy compared with AZ31 Mg alloy. By correlating the degradation behavior with the microstructure, galvanic corrosion was found to be the main reason behind the accelerated corrosion rate in AZ91 Mg alloy compared with AZ31 alloy. The phases on the corroded sample surfaces were examined by X-ray diffraction (XRD) method and scanning electron microscopy (SEM) and found that the corrosion products which were deposited on the surfaces provided protection against the chloride ions which was indicated by the decreased corrosion rates as immersion time was increased

    Normally, flight delays and cancellations have significant impact on airlines operations and passenger’s satisfaction. Flight delays reduce the performance of airline operations and make significant effect on airports on time performance. Previously statistical models have been used for flight delays analysis. This study was applied in Indian aviation industry and it has given statistical analysis of domestic airlines. In this research paper, we have applied Machine Learning models with the help of computational intelligence techniques for predicting airport transport management system. We have also applied computational intelligence techniques such as Particle Swarm Optimization (PSO) and Ant Colonization Optimization (ACO) to optimize the prediction model for delay period time and calculating the most optimal dependability. We have made comprehensive analysis of Data Efficiency Model for different airlines with various approaches as well as comparative analysis of accuracy for predicting airport model by using various machine learning models. In this study we have presented invaluable insights for the analysis of flight delay models

    Responses to Increased Moisture Stress and Extremes: Whole Plant Response to Drought under Climate Change

    Get PDF
    In this chapter, we tackle the physiology of plant water use from the angle of how this will be modified in a context of a changing climate. Two recent reviews cover a number of innovative aspects to drought research, in particular in relation to research on roots, and advocate the need to look at the soil–root–shoot–atmosphere water management in a comprehensive and dynamic manner (Vadez et al. 2007, 2008). In the present chapter, we revisit some of these aspects from the perspective of changing climatic conditions and explore the major issues that climate change will bring about, and how it will affect crop production and in particular under water-limited conditions. These issues can be broadly grouped into two categories: (1) thermodynamic aspects of the soil–plant–atmosphere water relations and (2) growth and development aspects

    Field experiments were conducted at DRR farm located at ICRISAT, Patancheru, in sandy clay loam soils during four seasons, Kharif 2008, Rabi 2008–2009, Kharif 2009 and Rabi 2009–2010, to investigate growth parameters, water-saving potential, root characteristics, chemical, biological, and microbial properties of rhizosphere soil, and grain yield of rice (Oryza sativa L.) by comparing the plants grown with system of rice intensification (SRI) methods, with organic or organic + inorganic fertilization, against current recommended best management practices (BMP). All the growth parameters including plant height, effective tillers (10–45 %), panicle length, dry matter, root dry weight (24–57 %), and root volume (10–66 %) were found to be significantly higher with in SRI-organic + inorganic over BMP. With SRI-organic fertilization, growth parameters showed inconsistent results; however, root dry weight (3–77 %) and root volume (31–162 %) were found significantly superior compared to BMP. Grain yield was found significantly higher in SRI-organic + inorganic (12–23 and 4–35 % in the Kharif and Rabi seasons, respectively), while with SRI-organic management, yield was found higher (4–34 %) only in the Rabi seasons compared to BMP. An average of 31 and 37 % of irrigation water were saved during Kharif and Rabi seasons, respectively, with both SRI methods of rice cultivation compared to BMP. Further, total nitrogen, organic carbon%, soil dehydrogenase, microbial biomass carbon, total bacteria, fungi, and actinomycetes were found higher in the two SRI plots in comparison to BMP. It is concluded that SRI practices create favorable conditions for beneficial soil microbes to prosper, save irrigation water, and increase grain yield
