Ray-based Deterministic Channel Modelling for sub-THz Band

Future wireless communications systems will require large network capacities beyond the capabilities of present and upcoming 5G technology. The trend of considering higher frequencies for their large bandwidths continues today into the sub-THz domain. The BRAVE project considers the frequencies in the 90-200 GHz spectrum, which have been considered in this paper. The challenges of channel modelling at sub-THz frequencies are described along with extensions made to a ray-based deterministic tool. The geographical and physical accuracies inherent to the ray-based tool are exploited to simulate two different scenarios. The first scenario is an indoor office scenario and the second is an outdoor in-street scenario. The application of the updated channel modelling properties of the ray-based tool provides interesting perspectives into the sub-THz channel modelling. This permits the development of realistic models for the evaluation, characterization and eventual deployment of such systems

Neurovascular structures at risk from proximal locking of retrograde femoral nails

The Richards retrograde femoral nail (Smith and Nephew 1997) is inserted into the medullary canal of the femur via an entry point in the intercondylar fossa, just anterior the anterior cruciate ligament. This particular implant requires insertion of both proximal and distal interlocking screws for maximal axial and rotational stability. The distal screws are inserted lateral to medial in a relatively safe area of the lower thigh using an external guide. The proximal locking screws by contrast are inserted 'freehand' at the level of the lesser trochanter in an anteroposterior direction using X-Ray control. The proximal thigh contains many vital neurovascular structures and it is the proximity of the femoral nerves and vessels which is of significant concern due to the relative inaccuracy of the freehand technique (Riina et al 1998). Hypothesis This led me to my first null hypothesis that 'proximal anteroposterior locking screws of retrograde femoral nails can be inserted in the proximal end of the femur through the proximal thigh without damage to the nerves and vessels'. To test this hypothesis we proposed to: 1). Dissect the main nerves and vessels of the thigh and describe their position and relation to the lesser trochanter. 2). Place investigative drill holes in a modified anatomical procedure to imitate insertion of the proximal anteroposterior locking screws. 3). Dissect the proximal thigh to determine whether important anatomical structures are at risk of being damaged by the proximal anteroposterior locking screws. The preliminary results of this first investigation lead to a second null hypothesis:- That the nerves and vessels of the upper thigh are at risk from proximal locking screws inserted in a lateral to medial direction in the upper thigh. To test this hypothesis we propose to; 4). Plan dissections to compare lateral to medial locking with anteroposterior locking, for use with a redesigned nail. 5). Finally we proposed a modified clinical trial of the redesigned nail. This would involve attaching the redesigned nail to the side of a volunteer's thigh and taking X-Rays in theatre to determine whether the redesigned nail could be adequately screened to allow its use in practice

Pronunciation as a Stumbling Block for the Saudi English Learners: An Analysis of the Problems and Some Remedies

Pronunciation is an area of L2 learning that has long been relegated to the status of secondary skill. However, it is a mistaken belief or wrong notion that correct pronunciation plays little role in communication. It is observed that in many cases, mispronunciation leads to unintelligibility of speech and/or misinterpretation of the message/information: a barrier to communication. This premise prompted the researchers to study the difficulty in pronunciation experienced by Saudi students. This paper is also an attempt at exploring the pronunciation problems faced by the Saudi students of English and aims to propound possible remedial measures.  The researchers have included students enrolled in the English departments and their teachers at two universities in Saudi Arabia. Primary data was collected from the students and their teachers using surveys, interviews, and classroom observation of students’ presentations. The study made some suggestions regarding materials that can help rectify the pronunciation of English among Saudi learners of English

Estimation of Hypsometric Integral and Groundwater Potential Zones of Amarja Reservoir Catchment, Karnataka, India using SRTM Data and Geospatial Tools

Hypsometric integral always play a significant role in watershed health condition. It is nothing but the total time taken in reduction of land area to its vile. Drainage network and studies of various landform features always help in the search of groundwater resources. Morphometric parameter of a drainage basin always helps to understand water use and land use of the basin. The present study aims to find out the geological stages through hypsometric integral values and groundwater potential zones using morphometric parameters to classify it into very good, good, moderate and poor zones using GIS tools. The total area of catchment is 544.76 km2, which is surrounded by Deccan traps. The catchment is further separated into 5 sub-basins on the basis of 4th order stream to get the more specific result. The SRTM (Shuttle Radar Topography Mission) data have been generated from USGS website and further analysed to identify the drainage pattern, slope, contours etc. using ArcGIS 10.0 software. The most important parameters like linear, areal and relief for groundwater investigation have been analysed. The analysis revealed that the hypsometric integral value of sub-basin IV of Amarja reservoir catchment is 0.30 which is showing the late mature stage of the basin. Apart from that, the values of sub-basins II, III and V are 0.54, 0.50 and 0.43 respectively, represent the mature stage while sub-basin I has an integral value of 0.67 which represents the young stage of the basin and it is more susceptible for erosion. Drainage pattern of the catchment could be mainly described as sub dendritic to dendritic. Drainage texture was found to vary from 0.41 to 1.16 which is an indicative of massive coarse to granular texture. An average bifurcation ratio of basin is estimated 3.51 which is an indicator of structural control over the basin. Slope values were found to be in a range from 0.71 to 5.73 degree which indicates very gentle to moderate slop

A study on oxygen independent fitness (anaerobic capacity) in pre-collegiate boys of Vijayapur, North Karnataka, India

Background: The anaerobic capacity is a useful concept, its application during exercise testing should considerably increase the information gained regarding cardiovascular function in health and disease. The objective was to evaluate oxygen independent fitness (anaerobic capacity) in pre-collegiate boys (age group of 16-18 years) of Vijayapur, North Karnataka, India.Methods: Eighty seven young adolescent healthy pre-collegiate boys volunteered for this study. The following parameters were recorded: Physical anthropometric parameters: body surface area, body mass index, body fat percentage, Physiological parameters: Blood pressure, physical fitness index test and anaerobic fitness step test. Correlation analysis and Z tests were used to analyze the obtained data.Results: Physical anthropometric parameters of the subjects were found within normal range. Statistically significant exercise induced rise in blood pressure were observed in physical fitness step test. Anaerobic capacity was correlated with body surface area, body mass index, body fat percentage and pre and post exercise blood pressure. Physical fitness index was not correlated with anaerobic capacity.  Conclusions:The physical fitness index was in good category, normal physiological response to exercise but physical fitness index not correlated with anaerobic capacity. Anaerobic capacity was found within normal range in pre-collegiate boys of age 16-18 years in study area. Ideal body mass index may not be possible in this age group.

Sampling Plan Using Process Loss Index Using Multiple Dependent State Sampling Under Neutrosophic Statistics

This paper presents the designing of a sampling plan using the process loss consideration for the multiple dependent state sampling under the neutrosophic statistics. The operating characteristics under the neutrosophic statistical interval method (NSIM) are developed to find the neutrosophic plan parameters of the proposed sampling plan. A non-linear optimization under NSIM is used to find the optimal neutrosophic plan parameters under the given conditions. The advantages of the proposed sampling plan are discussed over the existing sampling plans. A real example having some uncertain observations is given for the illustration purpose
