Abstract: In the last decades vehicle license plate recognition systems are as central part in many traffic management and security systems such as automatic speed control, tracking stolen cars, automatic toll management, and access control to limited areas. There are many techniques for license plate detection. The goal of this paper is study and evaluate some most important LPD algorithms and compared them in terms of accuracy, performance, complexity, and their usefulness in different environmental condition. This evaluation gives views to the developers or end-users to choose the most appropriate technique for their applications. Our study and investigation show that the dynamic programming algorithm is the fastest and the Gabor transform is the most accuracy algorithm compared to other algorithms.

Ramanathan Jeyaraman, Pralhad S. Patki
Open Journal of Urology (OJU) , 2012, DOI: 10.4236/oju.2012.223030
Abstract: Benign prostatic hyperplasia (BPH) is a condition intimately related to ageing. Currently available treatment options for the management of BPH have various limitations and associated adverse effects. A polyherbal formulation is claimed to be beneficial in patients with benign prostatic hyperplasia. This single blind, placebo-controlled study evaluated the clinical efficacy and safety of polyherbal formulation in BPH. Material and Methods: A total of 60 patients who were diagnosed as BPH and who were willing to give informed consent were included in the study. At the randomization visit, a detailed medical history was obtained and the patients underwent a thorough systemic examination and digital rectal examination. Routine blood analysis, urinalysis and serum levels of prostate specific antigen were carried out. Abdominal pelvic ultrasonography was done at entry and after completing the study. The severity of the urinary parameters was evaluated using American Urological Association symptom score. All the patients were randomized using random table into either polyherbal group (n = 30) or placebo (n = 30). Each patient received either polyherbal formulation or placebo in a dose of 2 capsules twice a day with meals for two months. All adverse events reported by the patients or observed by investigators were recorded. Statistical analysis was done according to the intention-to-treat principles. Analysis was performed between the groups using Fisher's exact test or unpaired \"t\" test (Independent t-test). Results: Fifty-six patients completed the study. There was a significant improvement in the mean AUA symptom score, PVR urine volume urinary hesitancy, intermittent flow, straining during urination, sense of incomplete micturition and frequency of night-time urination, in the polyherbal formulation group. Four patients from the placebo group withdrew from the study due to lack of benefit to the treatment. Conclusion: The beneficial clinical efficacy of polyherbal formulation observed in this study in the management of BPH could be due to the synergistic actions of its potent herbs. This polyherbal formulation was well tolerated and safe.
Studies on Dissolution Behaviour of Nanoparticulate Curcumin Formulation  [PDF]
R. Ravichandran
Advances in Nanoparticles (ANP) , 2013, DOI: 10.4236/anp.2013.21010

Curcumin is the main biologically active phytochemical compound of turmeric that has been widely used by ancient cultures throughout Asia. However the dissolution rate limited absorption and pre-absorption degradation limits its use as a potential therapeutic. In this study an attempt has been made to overcome the above limitations by curcumin delivery through nanotechnology. Nanocurcumin solid dosage formulations were prepared and studied for its dissolution behaviour. Considerable improvement in the dissolution behavior was observed in the drug nanocrystal-loaded solid dosage forms. This is expected to enhance the bioavailability of poorly soluble medicinal herbs such as turmeric in the body.

Open Journal of Modern Hydrology (OJMH) , 2013, DOI: 10.4236/ojmh.2013.33019
Abstract: The purpose of the study was to develop pedotransfer functions for determining saturated hydraulic conductivity (Ks). Pedotransfer functions (PTFs) for predicting soil physical properties used in determining saturated hydraulic conductivity, based on moisture retention characteristics, were developed. The van Genuchten moisture retention equation was fitted to measured moisture retention properties obtained from International Soil Reference and Information Centre (ISRIC) soils data base in order to determine parameters in the equation i.e. saturated soil moisture content (θs), residual soil moisture (θr), air entry parameter (α) and the pore size distribution parameter (n). 457 samples drawn from the data base were used to be the maximum possible sample size that contained the measured soils characteristics data required. Using statistical regression, mathematical relationships were developed between moisture retention parameters (response variables) and appropriately selected transformed basic soil properties (predictor variables). The developed PTFs were evaluated for accuracy and reliability. It was found that pedotransfer functions developed for θs produced the best performance in reliability compared to the remaining parameters yielding a correlation coefficient value of coefficient of determination (R2 = 0.76), RMSE = 2.09, NSE = 0.75 and RSR = 0.5 indicating good performance. Relatively poorest performance was obtained from the pedotransfer function developed for α which yielded a correlation coefficient, R2= 0.06, RMSE = 0.85 and a NSE of 0.02 reflecting the best possible equation derived for the parameter for use in predicting hydraulic conductivity. Out of the pedotransfer functions developed for each of the moisture retention parameters, the best performing PTF was identified for each parameter. The accuracy of the pedotransfer functions assessed based on R2 were for θs (R2 = 0.80), θr (R2 = 0.42), α
Partnership Evaluation in Local Authorities in Spain  [PDF]
Fernando Matías-Reche, Víctor J. García-Morales, M. Eugenia Senise-Barrio
Open Journal of Business and Management (OJBM) , 2013, DOI: 10.4236/ojbm.2013.12004
Abstract: The current work aims to evaluate the partnerships of various local authorities in Spain. The work considers a number of theoretical approaches to partnership, and reports the results of a survey investigating the state of the partnerships that various local authorities have participated in to help improve training and access to the labour market for the unemployed. Descriptive statistical analysis was used to evaluate these partnerships. The main findings indicate that the main partner, the driving force behind the partnership, makes a more positive evaluation of the partnership than the minor partners, and that the partnership dimensions that are most valued and hence contribute most to the success of the partnership are Promotion of the involvement of collaborators and relevant outside institutions, and Basic elements and realism of the partnership, while the dimensions that are least valued are Emergence of a work network, and Evaluation and learning. We also find that satisfaction with the partnership is conditioned by the intensity of the collaboration.

Open Journal of Medical Imaging (OJMI) , 2015, DOI: 10.4236/ojmi.2015.51004
Abstract: Purpose: This study was done to assess the role of ultrasound in diagnosis of obstructive jaundice and to identify the most common causes and symptoms. Materials and methods: The study took place in different Khartoum clinical centers and hospitals in the period between Jan 2014 and July 2014. A total of 150 patients with obstructive jaundice were examined using ultrasound machine, 3.5 - 7 MHz probe. Results: The study revealed that 65.33 of the study population with obstructive jaundice were female and 34.67% was male. The most common affected groups were 46 - 65 years old and 25 - 45 years old. The common causes of obstructive jaundice were biliary stones (61.33%) which were common in females and abdominal masses (32.67%) which were common in females, too. Nausea, yellowish discoloration and abdominal pain were the most common symptoms (98%, 97.33% and 96.67% respectively). The causes of obstructive jaundice showed significant difference between males and females (P-value = 0.002). Conclusion: Ultrasound was superior diagnostic tool in detecting and assessing biliary system obstruction, because it was easy, available, accurate and noninvasive. The ageing and gender were considered as risk factors of obstructive jaundice.
Smiley Faces: The Evaluation of Watches as a Function of the Time Displayed  [PDF]
Adrian Furnham, James King, Vladimir Kolzeev
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.614181
Abstract: Wristwatch advertisements show a preference for having the watch hands displaying the time 1:50 or 10:10 which suggest a “smiley face”. This paper reports two studies, one with students, the other with non-students. Participants rated six different watches showing six times on four different scales: perceived attractiveness, expensiveness, the income level of the typical wearer of the watch, and the sense of style of the typical wearer of the watch. Time shown had no effect on the ratings of the watches. Implications and limitations are considered.
School Evaluation: A Possible Dialogue between the History and Epistemology  [PDF]
Aldo Sena de Oliveira, Linsmar Nascimento Lenartovicz
Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.68014
Abstract: This article approaches the school evaluation according to historical and epistemological assumptions and the strategies inserted from its genesis to its application in the context of the contemporary school. The analysis is based on a historical narrative that contextualizes the concept of evaluation and its meaning as practices established from the beginning of humanity, such as its possible origin in China. We report the construction of new meanings for evaluation and its constitution as a stage in the educational process. In addition to the qualitative assignments, the evaluative course that culminates in the development of quantification forms, explained in the docimology, content orientation psychometry and in the intellectual quotient (IQ) analysis, is reported.
Institucionaliza??o da avalia??o na administra??o pública
Denis, Jean-Louis;
Revista Brasileira de Saúde Materno Infantil , 2010, DOI: 10.1590/S1519-38292010000500020
Abstract: this article approaches the subject of evaluation under the perspectives of a potential to promote changing in organizations, of its institutionalization conditions and strategies to be used. it begins with the assumption of belief 'to change situation', of the contribution to 'reality understand' and of the 'actors senses' about decision making. this approach is supported by the rising of a new professionalism in services and organizations management; in the increased complexity of problems and in the role of 'networks' and its relationship with governance. it emphasizes the legitimacy needed by evaluation to influence decisions. it points out three types of evaluations by means of practice and knowledge: goaloriented evaluation, theory-driven evaluation and that with participatory perspective and discuss about the incapacity to solve problems when using only one type of evaluation. as challenges to its institutionalization, it presents: capacity to carry out evaluation, consistent strategy for results publicizing and use capacity. the article ends taking into account that the institutionalization of evaluation presumes important changing in the use of power to decision making in public administration. it recommends a permanent debate of the possibilities of correct use of evaluators work and about its benefits for society and institutions.
