    For robots to be considered effective, they should be able to maneuver through 3D environments. To achieve such mobility, robots needs to be designed in such a way that would span various topographies. So, artificial intelligence algorithms have been developed to ensure agility of the robots when walking on murky topographies. In the current state of the art legged robots, there is still much progress need to be made in research to turn them into automobiles with great agility to be used in the real world utility and provide mobility in rough. GOAT leg as a means of artificial intelligence is still a new phenomenon. There still exists a number of preliminary tests that need to be done in accessing and in the characterization of the leg’s current performance and its implications in the future. This study seeks to develop and agility model which would be useful in ensuring that the robots remain agile in such complex environments. To do this, a simulation has been through Matlab analysis. Results of the current study showed that, 3-RSR was designed to ensure that a high fidelity proprioceptive force control would enable legs with the mechanically spring stiffness. Implications and future recommendations also discussed

    In HV substations, thermal effects of temperature and resulting heating losses have a profound impact on the life of substation equipment. In order to efficiently detect these irregular heating patterns occurring in substation, a non-intrusive infrared thermography (IRT) based technique is suggested for detecting these abnormal heat variations in the electrical .substation equipment. In order to analyze thermal images of the substation, manual analysis may consume a lot of time and efforts and also there is every possibility of human errors in detection of faults. Thus to automate process of thermography, image processing techniques have to be opted for. In this paper, the process of image processing methodology consisting of feature vector extraction and image classification based algorithm are proposed here. Initially, two of the intelligent image processing techniques i.e. feature vector extraction techniques, K-means clustering and Fuzzy C-means (FCM) clustering, are proposed here and their results will be compared with each other with respect to their performance and efficiency. Then the substation equipment condition will be further evaluated and classified using Support Vector Machine (SVM) classifier to classify thermal images into two categories as normal or abnormal. The programming of the above mentioned techniques is done using MATLAB software. The proposed classifier technique results indicate higher accuracy above 90%

    A partir de una sospecha de sarna sarcóptica en tres de cinco conejos albinos europeos (Oryctolagus cuniculus), mantenidos con fines experimentales, se hizo un examen general que reveló áreas multifocales de alopecia alrededor de los ojos, las fosas nasales y los labios. Se procesaron cortes de piel y un análisis de PCR con el objeto de identificar los ácaros. La histopatología de los cortes de piel mostró epidermis erupcionada y estrato córneo con una infiltración de células inflamatorias. El raspado o frotis de piel reveló la presencia de ácaros tanto en adultos como en huevos. Al examen microscópico, los ácaros adultos fueron identificados como Sarcoptes (S.) scabiei (Acari: Sarcoptidae). El análisis de muestras de los tres casos por PCR reveló una banda de 311 pb confirmando la infestación de S. scabiei en los conejos. La infección en conejos con S. scabiei puede representar un problema de salud pública de transmisión indirecta debida a la manipulación de conejos infestados. Hasta la presente, este es el primer reporte de infección por S. scabiei en conejos de Pakistán

    Spatiotemporal Analysis of Land Use / Land Cover in Swat, Pakistan Using Supervised Classification in Remote Sensing: 2000 to 2015

    Changes in land use and land cover affect the social, economic and natural aspects of any area. Mostly land use and land cover (LULC) changes are the result of population growth and human activities in the form of urban agglomerations and industrialization etc. Physical factors like soil structure and type, slope condition, topography are main aspects. Land use change defines the historical pattern that how people used that specific land which depends on the availability of resources and economic conditions. LULC changes may trigger the detrimental effects like increase in natural hazard events and changes in climatic patterns. Climatic pattern directly affects the precipitation, groundwater recharge, the amount of evapotranspiration and runoff generation. On regional and local scale, LULC change is a far-reaching issue because environment and climate condition depend on i

    Diagnosis and Identification of Zoonotic Diseases Associated with Cattle at Abattoirs: Current Trends and Future Prospectus

    Get PDF
    Zoonoses are illnesses and infections that spread spontaneously from animals to people. They account for over 70% of recently developing infectious illnesses. Meat from cattle is one of the main sources of red meat and essential element of human diet. Meat inspection (MI) is an important aspect to ensure the safety during handling and consuming of meat and meat by-products. Abattoir or modern slaughterhouse is the place where infections are acquired by the workers or veterinary professional as zoonoses. Bacterial zoonotic diseases such as erysipelothricosis, brucella, listeria, and anthrax and viral zoonotic diseases like cow pox, foot and mouth disease, and rift valley fever are causing great economic losses and are important in terms of zoonoses. These zoonotic diseases are mostly diagnosed at abattoir levels using conventional approaches; however, diagnosis and identification of these diseases using latest methods is an important aspect for ensuring meat safety and hygiene. This chapter will discuss the current trends and future prospects about diagnosis and identification of these zoonotic diseases

    Burden of waterpipe smoking and chewing tobacco use among women of reproductive age group using data from the 2012-13 Pakistan Demographic and Health Survey

    Background: Despite the general decline in cigarette smoking, use of alternative forms of tobacco has increased particularly in developing countries. Waterpipe (WP) and Chewing Tobacco (CT) are two such alternative forms, finding their way into many populations. However, the burden of these alternative forms of tobacco and their socio demographic determinants are still unclear. We assessed the prevalence of WP and CT use among women of reproductive age group in Pakistan. Methods: Data from the most recent Pakistan Demographic and Health Survey 2012–13 (n = 13,558) was used for this analysis. Information obtained from ever married women, aged between 15 and 49 years were analyzed using two separate data subgroups; exclusive WP smokers (total n = 12,995) and exclusive CT users (total n = 12,771). Univariate and Multivariate logistic regression analyses were conducted and results were reported as crude and adjusted Odds Ratio with 95 % confidence intervals. Results: Prevalence of WP smoking and CT were 4 % and 2 %, respectively. After multivariate adjustments, ever married women who were: older than 35 years (OR; 4.68 95 % CI, 2.62–8.37), were poorest (OR = 4.03, 95 % CI 2.08–7.81), and had no education (OR = 9.19, 95 % CI 5.10–16.54), were more likely to be WP smokers. Similarly, ever married women who were: older than 35 years (OR = 3.19, 95 % CI 1.69–6.00), had no education (OR = 4.94, 95 % CI 2.62–9.33), were poor (OR = 1.64, 95 % CI 1.07–2.48) and had visited health facility in last 12 months (OR = 1.81, 95 % CI 1.22–2.70) were more likely to be CT users as well. Conclusion: Older women with lower socio-economic profile were more likely to use WP and CT. Focused policies aiming towards reducing the burden of alternate forms of tobacco use among women is urgently needed to control the tobacco epidemic in the country

Gross examination revealed multifocal areas of alopecia around the eyes, nostrils and lips. Skin snips were processed using PCR for the molecular identification of the suspected mites. Histopathology of the skin snips showed erupted epidermis and stratum corneum with an infiltration of inflammatory cells. Skin scraping examination revealed the presence of adult mites as well as eggs. Microscopic taxonomy identified the adult mites as Sarcoptes (S.) scabiei (Acari: Sarcoptidae). The results of PCR indicated a 311 bp band from all the three cases, which confirmed the S. scabiei infestation in rabbits. Sarcoptes scabiei may be a public health concernthrough direct transmission from rabbits infested with S. scabiei through handling. To the best of our knowledge, this is the first report of S. scabiei infection in rabbits from Pakistan
