Opis:
The unrelated design has been shown to improve the efficiency of a randomized response method and reduces respondents’ suspicion. In the light of this, the paper proposes a new Unrelated Randomized Response Model constructed by incorporating an unrelated question into the alternative unbiased estimator in the dichotomous randomized response model proposed by Ewemooje in 2019. An unbiased estimate and variance of the model are thus obtained. The variance of the proposed model decreases as the proportion of the sensitive attribute ?_A and the unrelated attribute ?_U increases, in contrast to the earlier Ewemooje model, whose variance increases as the proportion of the sensitive attribute increases. The relative efficiency of the proposed model over the earlier Ewemooje model decreases as ?_U increases when 0.1??_A? 0.3 and increases as ?_U increases when 0.35??_A? 0.45. Application of the proposed model also revealed its efficiency over the direct method in estimating the prevalence of examination malpractices among university students; the direct method gave an estimate of 19.0%, compared to the proposed method’s estimate of 23.0%. Hence, the proposed model is more efficient than the direct method and the earlier Ewemooje model as the proportion of people belonging to the sensitive attribute increases.

Opis:
Pressure-sensitive adhesives (PSAs) represent a system that actually dates back to the invention of the self-adhesive articles in 1935 when R. Stanton Avery produced the first coating unit using a wooden cigar box with two holes cut in the bottom. PSAs can be defined as a special category of adhesive which in dry form are permanently tacky at room temperature [1–4]. Since 1960s, silicone pressure-sensitive adhesives have found many uses. They are used in industrial plants, as tapes for joining materials with low surface energy, as well as in the sectors of electrical and electronic, medical care, health care and automotive industry. For about 10 years there has been great interest in new uses for the silicone PSA, particularly for medical and industrial belts. The above examples describe a growing range of potential commercial applications of silicone pressure- -sensitive adhesives. Silicone pressure-sensitive adhesives typically consist of large segments of the silane-functional silicone polymers and silicone resins (MQ). It is well known that silicone pressure-sensitive adhesives because of their unique properties are special-purpose products. The combination of the properties of silicones such as high flexibility of connections Si-O-Si, low intermolecular interaction, low surface tension, excellent thermal stability and transparency for UV radiation, excellent electrical properties, high chemical resistance and weather resistance makes silicone adhesives have improved properties compared to other typical polymeric organic adhesives. Due to the low surface tension of silicone adhesives, adhesive is easily spread on the surface of various materials [4–9]. The properties of silicone pressure sensitive adhesives (Si-PSA) crosslinking thermally by organic peroxides (according to a radical mechanism) depend on the type and concentration of crosslinker used. Benzoyl peroxide (BPO) and 2,4-dichlorobenzoyl peroxide (DClBPO) are the most commonly used peroxides the industry. Increasing the content of BPO or DClBPO in a predominantly affects significantly increase the cohesion, while reducing the adhesion of tested adhesives [1, 5, 6]. With the market testing of pressure sensitive adhesives and literature studies clearly show that there were no studies to date on the process of UV-curing silicone pressure sensitive adhesives; and there is no sales sided adhesive tapes, silicone crosslinked by UV radiation.

For about 10 years there has been great interest in new uses for the silicone PSA, particularly for medical and industrial belts. The above examples describe a growing range of potential commercial applications of silicone pressure-sensitive adhesives [2, 7, 9–11]. In contrast to the pressure-sensitive adhesives organic silicone pressure-sensitive adhesives show much better performance by this well known it happened that are used to obtain self-adhesive materials for special purposes. Si-PSA usually consist of large segments of the silanol-functional silicone polymers, and silicone resins. Polymeric chains comprising the silicone resins include methyl and phenyl groups thus are very little reactive chemicals. In order to obtain the best adhesion-cohesion balance are used crosslinked thermally in a temperature range of 120–150°C by using organic peroxides. Peroxides most commonly used in industry benzoyl peroxide (BPO) and 2,4-dichlorobenzoyl peroxide (DClBPO). Silicone pressure- -sensitive adhesives are characterized by high flexibility of connections Si-O-Si, low impact intermolecular, low surface tension, excellent thermal stability and transparency for UV radiation, excellent electrical properties, high chemical resistance and weather resistance [2, 6, 7, 14]. In the available literature the montmorillonite and kaolin modified silicone pressure-sensitive adhesives which exhibited increased thermal resistance are reported. The thermal properties of adhesives compositions are better to compared with “pure” silicon composition without any filler [6, 12–14].

Opis:
This work concerns controlled Markov chains with finite state space and nonnegative rewards; it is assumed that the controller has a constant risk-sensitivity, and that the performance ofa control policy is measured by a risk-sensitive expected total-reward criterion. The existence of optimal stationary policies isstudied within this context, and the main resultestablishes the optimalityof a stationary policy achieving the supremum in the correspondingoptimality equation, whenever the associated Markov chain hasa unique positive recurrent class. Two explicit examples are providedto show that, if such an additional condition fails, an optimal stationarypolicy cannot be generally guaranteed. The results of this note, which consider both the risk-seeking and the risk-averse cases, answer an extended version of a question recently posed in Puterman (1994).

Forest cover in the hill regions is essential to maintain environmental, economic and ecological balances. North Bengal accounts for 3,086 sq km (26 %) of the 11,876 sq km area of classified forests in the state, and for nearly 5,000 sq km (40 %) of all land under tree cover. Khumani is a Village (26.84o N, 88.60o E) in Gorubathan Block in Darjeeling District of West Bengal State, India. The survey work was done in December, 2014 by visiting the Khumani Forest Village (established in 1949) of upper Kumai and the primary data were gathered through field survey and direct contact with common people and authorized centers of the region. Surveys on the demography, agriculture, livestock management, water management, education, culture, health, waste management, disaster management, transport, biodiversity, human animal conflict were done in this area. Topographic map of the area was prepared by using the database of National Atlas and Thematic Mapping Organization (NATMO), Kolkata office. In every phase of the survey work, pictorial documentation was done. In spite of being positioned in a diverse and sensitive ecological zone, the village is not adequately managed. There is an urgent need for implementing sustainable management systems in the areas for the betterment of the socio-environmental structures. Some of the possible management strategies have been suggested for maintaining the social, environmental, economic and ecological balance of the region. Proper funds should be raised to conserve and manage these ecologically important zones of north Bengal, which should be one of the main focuses of future researches.

Although the phenomenon of otoacoustic emission has been known for nearly 30 years, it has not been fully explained yet. One kind of otoacoustic emission is distortion product of the otoacoustic emission (DPOAE). New aspects of this phenomenon are constantly discovered and attempts are made to interpret correctly the obtained results. This paper discusses a new method of measuring DPOAE signals based on double phase-sensitive detection, which makes possible a real-time measurement of the DPOAE signal amplitude and phase. The method was applied for measurements of DPOAE signals in guinea pigs. Sample records are presented and the obtained results are discussed.

Opis:
Pressure-sensitive adhesives (PSA) are a group of adhesive-based macromolecular polymers which are characterized by good (satisfying the requirements of industrial) adhesion and cohesion; high temperature stability during use, excellent aging resistance and constant tear strength. In 1935, the concept of self-adhesive glue, wherein the obtained self-adhesive product of the invention R. Stanton Avery, was firstly developed. From many types of adhesives, the most common adhesives are acrylics pressure-sensitive adhesives [1–3]. In most cases, self-adhesive adhesives do not exhibit good conductive properties, whereas conductivity grades are classified in the group of insulators. In order to improve their conductive properties, studies have been conducted on the modification of polymers in adhesive compositions, where at least one of the components exhibited conductive properties (e.g. polymers with conjugated π-bonded polymers along polymeric chains). However, the best effects were obtained by adding conductive fillers such as metal (copper, aluminum), specially modified soot, nanotubes or graphene, carbon fibers, metallized glass and conductive fibers. This allowed the creation of electrically conductive compositions characterizing by conductivity in the range from 10–2 to 102 S/cm. This relatively high conductivity is the result of the percolation of conductive filler molecules into an insulating matrix or tunneling between electrically conductive molecules [10, 11]. Acrylate pressure-sensitive adhesives with conductive fillers have found a number of important industrial applications, especially in the electronics industry. Pressure- sensitive adhesives, such as self-adhesive tapes or adhesive films, are used as heating elements, sensors or conductive gums. Due to their good performance, they can be used to connect solar panels or glue small components in the microelectronics industry. They also can be used to discharge static charges from the surface – used as flexible drainage connections – especially in places where the spark is undesirable and can be dangerous. They are used as heating elements [10, 12, 27].

To restore the quality of education, the 2013 curriculum reform in Indonesia urged teachers to employ pupil-centered, thematic problem-based learning (PBL). This study examined whether the PBL collaborative learning enabled students to learn better and in an equal manner through an array of cross-cutting aspects like race, social class, and gender. The presented study involved two teacher colleges and randomly assigned undergraduate classes that were taught with the use of PBL practices while other comparable classes were taught through traditional lecturing. It was found that the students in the experimental group performed better and more equalized than those in the other group. This is to assist the teacher colleges to teach their student-teachers to design and practice more engaging classes where boys and girls are given equal chances to foster their potentials to the fullest.

Opis:
Support Vector Machines (SVM) with RBF kernel is one of the most successful models in machine learning based compounds biological activity prediction. Unfortunately, existing datasets are highly skewed and hard to analyze. During our research we try to answer the question how deep is activity concept modeled by SVM. We perform analysis using a model which embeds compounds’ representations in a low-dimensional real space using near neighbour search with Jaccard similarity. As a result we show that concepts learned by SVM is not much more complex than slightly richer nearest neighbours search. As an additional result, we propose a classification technique, based on Locally Sensitive ashing approximating the Jaccard similarity through minhashing technique, which performs well on 80 tested datasets (consisting of 10 proteins with 8 different representations) while in the same time allows fast classification and efficient online training.
