Yet Another Method for Image Segmentation based on Histograms and Heuristics

We introduce a method for image segmentation that requires little computations, yet providing comparable results to other methods. While the proposed method resembles to the known ones based on histograms, it is still different in the use of the gray level distribution. When to the basic procedure we add several heuristic rules, the method produces results that, in some cases, may outperform the results produced by the known methods. The paper reports preliminary results. More details on the method, improvements, and results will be presented in a future paper

Ceramic Materials Based on Clay Minerals in Cultural Heritage Study

The artifacts belonging to the ceramic heritage are mostly based on all clay types used by humans over the ages, because the sources of clays were easily available and people were interested to produce ceramics and pottery. This is the reason why the conservation of cultural heritage is of great concern. Ceramics (Greek κεράμιον Keramion) is a material obtained by shaping and firing clay. In the Romanian history, many ceramic pieces, of great diversity, have been discovered, and most of them are used in traditional households. Ceramic materials based on clay minerals in cultural heritage (ceramic heritage) involve techniques of characterization of raw materials and ceramic objects based on clays, discovered in different archaeological sites, leading to some results about the production technology, provenance, authentication, and historical appartenance on Romanian territory. The chemical composition of ancient ceramics and pigments decorating them, excavated from different Romanian archaeological sites, suggested a chemical composition of ceramic based on clay minerals (kaolinite, illite, and smectite), while the pigments belonging to them contained red pigments (hematite or ocher), manganese oxides (brown pigments), and magnetite or carbon of vegetable origin (black-pigmented layers)

Patient’s interest towards interconnection and social implication with trainer doctor model

OED and the dictionary of the world defines a "doctor" 700 years ago and today as a "teacher". The root word for the word doctor derives from Latin "docere", which means "to teach". The doctor contributes to educating patients about a number of medical conditions (the patient is experiencing a number of diseases). In essence, the doctor has the role as a teacher. Doctor-patient interaction works on relational models. The physician-trainer paradigm is required to be introduced to improve patient status. The physician-trainer model is a participatory model that results in achieving the patient's well-being and improving his/her health; the physician uses his or her capacity as a trainer, that is, he has the ability to form and instill adequate conduct for each patient. In this paper, besides highlighting the appetence for the relationship between the trainer and the patient, we tried to quantify the patient's acceptance of the treatment with/without continuous monitoring of the disease (chronic diseases), the degree of reasonableness in accepting the therapeutic behavior, and lastly how the individual feels the change of his status in the patient. The study was conducted on a total of 217 subjects (125 female subjects and 92 male subjects). The applied questionnaire contained 18 questions, structured to help us confirm or not the study's objectives. The results obtained will show us the level of appetite for the trainer-patient relationship

ASPECTS REGARDING THE RECOVERY OF THE ANKLE SPRAIN BY MYOFASCIAL TECHNIQUES

Introduction: A sprained ankle is an injury that occurs when you roll, twist or turn your ankle in an awkward way. This can stretch or tear the tough bands of tissue (ligaments) that help hold your ankle bones together. The incidence of training injuries is almost constant for players between the ages of 13 and 19, with the majority of injuries ranging from 1 to 5 injuries per 1,000 hours of training, while younger players have lower incidences. The incidence of injuries during the match tends to increase with age, in all age groups, with an average incidence of about 15 to 20 injuries per 1,000 hours of play in players over 15 years of age. Objective: The aim of this study is to verify the efectiveness of an individualized kinetic program in association with myofascial techniques. Methods: The myofascial techniques used are IASTM (Ergon therapy), dry needling, cupping and kinesiotaping. In this study a 18 years old football player was included. The evaluation was performed by the Biodex (for the muscle strength) and lunge test (for the range of motion). Results: After a month o treatment, our patient improved his strength and range of motion. Conclusion: Studies have shown that these techniques of myofascial release provide a huge effectiveness on the flexibility of the muscles, having even much more efficacy than stretching. Using myofascial techniques, has a much quicker result on the recuperation of the ankle sprain offering a great efficacy on the total recuperation of the pacient.

Aspecte privind recuperarea entorsei de gleznă prin tehnici miofasciale. Introducere: O entorsă a gleznei este o leziune care apare atunci când vă rostogoliți, răsuciți sau întoarceți glezna într-un mod neobișnuit. Acest lucru poate întinde sau rupe benzile dure de țesut (ligamente) care ajută la menținerea oaselor gleznei împreună. Incidența accidentărilor la antrenament este aproape constantă pentru jucătorii cu vârste cuprinse între 13 și 19 ani, majoritatea accidentărilor variind de la 1 la 5 accidentări la 1.000 de ore de antrenament, în timp ce la jucătorii mai tineri incidența este mai scăzută. Incidența accidentărilor în timpul meciului tinde să crească odată cu vârsta, la toate grupele de vârstă, cu o incidență medie de aproximativ 15 până la 20 de accidentări la 1.000 de ore de joc la jucătorii de peste 15 ani. Obiective: Scopul acestui studiu este de a verifica eficacitatea unui program kinetic individualizat în asociere cu tehnici miofasciale. Metode: Tehnicile miofasciale utilizate sunt IASTM (Ergon therapy), dry needling, cupping și kinesiotaping. În acest studiu a fost inclus un jucător de fotbal în vârstă de 18 ani. Evaluarea a fost efectuată cu Biodex (pentru forța musculară) și testul fandare (pentru amplitudinea de mișcare). Rezultate: După o lună de tratament, pacientul și-a îmbunătățit forța și amplitudine de mișcare. Concluzii: Studiile au arătat că aceste tehnici de eliberare miofascială oferă o eficiență uriașă asupra flexibilității mușchilor, având chiar mai multă eficacitate decât stretching-ul. Utilizarea tehnicilor miofasciale are un rezultat mult mai rapid la recuperarea entorsei gleznei oferind o mare eficacitate asupra recuperării totale a pacientului. Cuvinte cheie: terapie manuală, recuperare, entorsă de gleznă

Psychosomatics of the impact of dental radiological investigations on the patient

Radiological diagnosis in dental medicine is of overwhelming importance, helping the dentist to develop and justify his final diagnosis. They are increasingly common situations where diagnosis can only be determined radiologically. It is the patient's right to be informed about his or her state of health and at the same time we add a doctor's duty. In our material, we tried to highlight the impact on the patient the conducting and communicating the outcome of radiological investigations, to prove that there is fear of irradiation and to understand how the radiological image that demonstrates a poor orodental health entails the need for rehabilitation. This statistical study was performed on a total of 223 subjects (128 female subjects and 95 male subjects). The subjects of the study were asked questionnaires whose questions highlight the confirmation or rejection of the proposed objectives. The results obtained will show to what extent the patients have quantified the requirements of the questionnaires. Obtaining responses with a slightly surprising character certifies the rigor of our research

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis
