Weighted Residual Target Proximity Kernel Pursuit Regression based Students Admission Prediction for Higher Education

 Education plays a significant role in providing individuals with the knowledge, skills, and tools needed for personal as well as academic growth. Due to the increasing number of higher education graduates, student admissions process is essential for selecting qualified candidates for admission in a universities or colleges. An admissions system with suitable and reliable criteria is important to select students who performing well academically as well as other activities at institutions. Therefore, each university or college needs to use the best possible techniques for analyzing the history of a student's academic performance and other extracurricular activities before admitting them. Education Data Mining (EDM) involves the application of data mining techniques to large educational databases with the aim of discovering useful information.  Several machine learning techniques have been developed in this area, but there are issues related to time efficiency and errors in prediction of admissibility for higher education. To address the aforementioned challenge, a novel technique named Weighted Residual Target Proximity Kernel Pursuit Regression (WRTPKPR) has been developed. This technique aims for the accurate prediction of graduate admissions with minimal error by mapping the course to the students based on their interests and CGPA secured. The proposed WRTPKPR technique includes three major phases namely data acquisition, preprocessing, and feature selection for accurate predictive analytics.Top of Form  The WRTPKPR technique initiates by collecting information from the dataset during the data acquisition phase.  Following data acquisition, the WRTPKPR technique undergoes data preprocessing to transform the input data into a suitable format for accurately predicting whether the student is admissible or not.  Two key processes are conducted in the data preprocessing phase, namely, missing data imputation and outlier data detection. In the initial step, the Horvitz–Thompson Weighted imputation method is applied to generate missing data points based on other known data points in the dataset. In the second step, an outlier detection method based on the maximum normalized residual test is employed to identify data points that significantly deviate from the rest of the data point in the dataset.  With the preprocessed dataset, the target feature selection process is conducted by applying Kernel Cook's Proximity Projection Pursuit Regression. Based on the selected target features, accurate admission predictions are made for higher education graduates with minimal time consumption. Experimental evaluation considers factors such as admission prediction accuracy, precision, recall, F1-score and admission prediction time. The results demonstrate that the proposed WRTPKPR technique achieves efficient performance outcomes, including higher accuracy, precision, with minimized time

Water use of irrigated oil palm at three different arid locations in Peninsular India

The water requirement of irrigated oil palm (Elaeis guineensis) in Andhra Pradesh, Karnataka and Maharashtra, India, were estimated using the Penman-Monteith equation. Microclimate parameters measured using an automated weather station showed that the 3 geographically separated sites also had climatic differences. The temperature at the study sites ranged between 12 and 35°C and the vapour pressure deficit (VPD) of the atmosphere ranged between 0.3 and 4.5 kPa. Stomatal conductance measured on fully irrigated plants showed a maximum of 500 mmol m-2 s-1. The stomatal conductance was highly correlated with the VPD. Closure of stomata started when the VPD was greater than 1.0 kPa. The stomatal conductance was severely reduced when the VPD reached values >1.9 kPa. All the sites had a prolonged dry season. At none of the sites could oil palm be grown as a rainfed crop. Water loss by transpiration as estimated for a dry day (without rain) ranged from 2.0 to 5.5 mm. The transpiration/evaporation ratio was approximately 0.8 at all 3 locations

Compact steep-spectrum sources from the S4 sample

We present the results of 5-GHz observations with the VLA A-array of a sample of candidate Compact Steep Spectrum sources (CSSs) selected from the S4 survey. We also estimate the symmetry parameters of high-luminosity CSSs selected from different samples of radio sources, and compare these with the larger sources of similar luminosity to understand their evolution and the consistency of the CSSs with the unified scheme for radio galaxies and quasars. The majority of CSSs are likely to be young sources advancing outwards through a dense asymmetric environment. The radio properties of CSSs are found to be consistent with the unified scheme, in which the axes of the quasars are observed close to the line of sight, while radio galaxies are observed close to the plane of the sky.Comment: accepted for publication in mnras; 8 pages, figure 1 with 21 images, and two additional figures; 2 table

Socio-economic Impact Assessment of Livelihood Security in Agriculture, Animal Husbandry and Aquaculture on the Tsunami-hit Lands of Andaman

Indian subcontinent is highly vulnerable to major natural disasters such as earthquakes, cyclones, floods, droughts, landslides and bushfires. Tsunami, which is a recent addition to this list, had occurred in the early morning of 26th December 2004, after a massive earthquake of 9.2 magnitude on the Richter scale in Andaman & Nicobar islands, resulting in the submergence of large area of farmland, and subsequent drying up of water bodies. It caused moisture stress for the standing crops, livestock and fisheries and affected the livelihood of the people to a large extent. In this context, the present study has been carried out to make the socio-economic impact assessment of livelihood security in agriculture, animal husbandry and aquaculture on the tsunami-hit lands of Andaman. Data have been collected from 150 sample respondents and the survey has been conducted for two periods, pre-tsunami and post-tsunami. The results have indicated that tsunami has ravaged the households, standing crops, farm inputs such as seed, feed and implements, livestock and poultry population, their sheds, fish ponds, etc., thereby affecting the basic livelihood security of the people in Andaman. The rehabilitation measures taken by the government and NGOs have improved their livelihoods by reviving agriculture considerably in the subsequent years and by creating employment opportunities in various farm and non-farm activities. The paper has suggested creating profitable livelihood security to vulnerable sections of the society in the existing socio-economic penury with holistic intervention of the community, government and NGOs.Agricultural and Food Policy,

Anlaysis of Scar Revision

INTRODUCTION: Scar is defined as the trace of healed wound, sore or burn. A fault or blemish remaining as a trace of some former condition or resulting from some particular cause. In Medical Terminology, a scar is non regenerative wound Healing. Preferred scar is the one that has matured early without contraction or increase in width, formation of collagen that is not more than necessary for its strength. Scar Revision is a commonly requested procedure that is performed frequently by the majority of plastic surgeons. The holistic approach to the patient is paramount in scar revision. Scar revision is a process that requires careful assessment, technical expertise and recognition of the underlying psychosocial issues if a satisfactory outcome is to be achieved. Each patient is different and it is in appropriate simply to select standard operation. AIM OF THE STUDY: The aim of the study is to analyse the causes of scar which include Road Traffic Accidents, Assault, Burns, Chronic infections & Acne, • To analyse the reasons for scar revision with include - functional aesthetic, psycholgoical problems. • To discuss medical / surgical treatment options. • To assess the scar post operatively using Beausang's clinical score and subjective patient acceptance. • To find out incidence of reference from doctors. • To find out Technical differences in the procedure in our set up. MATERIALS AND METHODS: 25 patients of facial scars of varied etiology were taken up for study in the period of 2½ years from August 2005 March 2007. 10 female patient, 15 male patients. Average age group 15-25 years almost all are in same age group. Etiology of Scar: Assault - by knife – 6, Road Traffic accidents – 9, Burns – 6, Others – 4. No. of patients referred by medical professionals – 6, Self referral – 19. All patients underwent scar revision surgery, assesed by Beansang;s clinical score - post operatively. Procedure done are linear excision + closure – 12. `Z' plasty – 6, `W' plasty -2, serial Excision – 4, Tissue expansion – 1, Post operative score - 12 patients - score of 8-9, 8 patient - score of 10-12, 4 patients – 13, 1 patient – 14. 5 patients were not satisfied with result. 20 patients were satisifed. Operative Procedure : Elliptical Closure All cases are done under local infiltration anaesthesia - except one cast of tissue expansion of neck -which was done order GA. 1% xylocaine with adrenaline is used. Areas cleaned, draping done. Scar markings dones before infiltration. Local infiltration anasthesia given. Scar is excised. Skin flaps undermined, and especially at corners. Hemostasis obtained with bipolar diathermy Dermal subdermal sutures applied with 4-0 prolene Skin sutured with either simple sutures using 5-0 prolene or subcuticular suture were 3-0 nylon. Compression dressing given. Post op.followup. Wound inspected after 48 hrs - left opened after 48 hours. Suture removal of 6th day. After 3 weeks scar massage. Aloevera cream applied two times a day. Scar assessed after 4 weeks / 3 / and 6 months. OUTCOME OF THE STUDY: 1. Most of the patients came for scar revision in the age group of 15-30 years - especially they came for scar treatement when they are preparing for marriage. All the patients have thought that after plastic surgery treatment there will be no scars. 2. Most of the patients came for oesthetic reasons only Functional problems like painful scar / or contour deformity in face relatively rare. 3. Most of the scars due to Assault with knife, Road traffic accidents, burns. 4. After surgical revision most of the patients (18/25) were satisfied with the result. 5 patients were not satisfied. Of the 5, 2 patients developed scar contracture and bad result. 5. Medical treatment will be useful in superfical scars, and for prevention a severity and scar. 6. Post operative Beausang's score - 12 patients score - 8-9, 8 patients score - 10-11, 3 Patients score - 13, 2 Patients score - 14, 7. Reference from primary physicians to specialist for scar management is compartively less. 8. Using various techniques like `Z' plasty or `W' plasty, depends upon location and scar, direction of scar relate to RSTL - if used properly gives good results. 9. Scar revision in post traumatic scar gives good results than post burn scar CONCLUSION: People have myth that after scar revision by plastic surgeons, they won't have any scar, but that is not true. Always there will be remaining scar. When we explained these to patients, 10% of patients - refused surgery. Z Plasty in face - size of the `Z' is not more than 3mm, so that scar size will not increase. Dermo epidemal suture using 4-0 prolene gives consistantly good results. Scar revision post traumatic scar gives better result them post burn scar. Dermabrasion will not be useful in post burn scar due to absence of dermis. `W' plasty - used in face especially forehead, cheek where limbs of `W' runs parrells to reliving skin tension lines. `Z ' plasty we used whenever there is need for lengthening of scar, to break it small segments also to get along the RSTL lines. Post operative application of Allovera gel alongwith scar massage significantly reduces scar severity

A Survey on Adaptation Strategies for Mutation and Crossover Rates of Differential Evolution Algorithm

Differential Evolution (DE), the well-known optimization algorithm, is a tool under the roof of Evolutionary Algorithms (EAs) for solving non-linear and non-differential optimization problems. DE has many qualities in its hand, which are attributing to its popularity. DE also is known for its simplicity in solving the given problem with few control parameters: the population size (NP), the mutation rate (F) and the crossover rate (Cr). To avoid the difficulty involved in setting of suitable values for NP, F and Cr many parameter adaptation strategies are proposed in the literature. This paper is to present the working principle of the parameter adaptation strategies of F and Cr. The adaptation strategies are categorized based on the logic used by the authors, and clear insights about all the categories are presented

Comparative tolerance of Pinus radiata and microbial activity to copper and zinc in a soil treated with metal-amended biosolids

A study was conducted to evaluate the effects of elevated concentrations of copper (Cu) and zinc (Zn) in a soil treated with biosolids previously spiked with these metals on Pinus radiata during a 312-day glasshouse pot trial. The total soil metal concentrations in the treatments were 16, 48, 146 and 232 mg Cu/kg or 36, 141, 430 and 668 mg Zn/kg. Increased total soil Cu concentration increased the soil solution Cu concentration (0.03-0.54 mg/L) but had no effect on leaf and root dry matter production. Increased total soil Zn concentration also increased the soil solution Zn concentration (0.9-362 mg/L). Decreased leaf and root dry matter were recorded above the total soil Zn concentration of 141 mg/kg (soil solution Zn concentration, >4.4 mg/L). A lower percentage of Cu in the soil soluble + exchangeable fraction (5-12 %) and lower Cu2+ concentration in soil solution (0.001-0.06 μM) relative to Zn (soil soluble + exchangeable fraction, 12-66 %; soil solution Zn2+ concentration, 4.5-4,419 μM) indicated lower bioavailability of Cu. Soil dehydrogenase activity decreased with every successive level of Cu and Zn applied, but the reduction was higher for Zn than for Cu addition. Dehydrogenase activity was reduced by 40 % (EC40) at the total solution-phase and solid-phase soluble + exchangeable Cu concentrations of 0.5 mg/L and 14.5 mg/kg, respectively. For Zn the corresponding EC50 were 9 mg/L and 55 mg/kg, respectively. Based on our findings, we propose that current New Zealand soil guidelines values for Cu and Zn (100 mg/kg for Cu; 300 mg/kg for Zn) should be revised downwards based on apparent toxicity to soil biological activity (Cu and Zn) and radiata pine (Zn only) at the threshold concentration. © 2013 Springer-Verlag Berlin Heidelberg
