Analysis and interpretation of the micromechanical properties measurements of electrodeposited nickel coatings on different substrates
Get PDFFine-grained nickel coatings were electrodeposited by direct current (dc) regime onto different substrates: polycrystalline cold-rolled copper, polycrystalline brass and single crystal (100)-oriented silicon. These composite structures belong to different type of laminated composite systems. The influence of the substrate material and coating plating parameters on microstructural and mechanical properties, such as hardness and adhesion, was characterized by the Vickers microindentation test for different loads. Above critical indentation depth (usually around 10% of the coating thickness), the measured hardness is the so-called “composite hardness”, because the substrate participates in the plastic deformations during indentation. Three composite hardness models (Korsunsky, Chicot-Lesage and Chen-Gao), constructed on different principles, were chosen for fitting the experimental results in order to determine the coating hardness and the critical reduced depth as the adhesion parameter. The coating hardness is mainly influenced by the current density, because increase in current density leads to decrease in grain size and increase in coating hardness. The critical reduced depth as the parameter of adhesion depends on the substrate material
Kun’s ideas of scientific revolutions and the objectivity of science
Get PDFKun’s The Structure of the Scientific Revolutions triggered the avalanche of criticism
and represents the most conducive and most critical work of the sixties, until the eighties of
the twentieth century, in which the problems of understanding scientific knowledge are
discussed. The development of science was understood as a gradual process during which
the stages of normal science and scientific revolutions were being shifted. Boldly, by
introducing new concepts in the history of philosophy of science, he has encountered many
opponents, but also gained many followers. In this paper, we tried to present Kun’s
understanding of the progress in science and criticism of his greatest opponents, with a
reference to the scientific revolutions in social sciences. We also tried to answer the
question of whether the scientific revolutions have been depleted and what is happening
with the objectivity of science.Кунова књига Структура научних револуција покренула је лавину критика и
представља најпревођеније и најкритикованије дело од шездесетих, па све до осамдесетих година двадесетог века, у коме се расправља о проблемима разумевања научног сазнања. Развој науке схватио је као постепени процес, током којег се смењују
етапе нормалне науке и научних револуција. Смело уводећи нове појмове у историју
филозофије науке, добио је много противника, али и много пратилаца. У раду смо
покушали да прикажемо Куново схватање прогреса у науци и критике његових највећих опонената, са освртом на научне револуције у друштвеним наукама. Такође,
покушали смо да одговоримо на питање да ли су научне револуције исцрпљене и
шта се дешава са објективношћу науке
Application of artificial intelligence in detection of DDos attacks
No full textServices distributed over the Internet are ranging from entertaining and informative to those whose availability must not be interrupted because it affects the quality of life, but also safety and health. Due to its importance, the global computer network is a desirable target, attacks are continually taking place, and the damage is more than considerable. Among the many types of attacks, one of the most effective, given the relationship between the damage done and the challenge to be prevented, detect and control, are DDoS attacks. This paper discusses the phases, components, categories, and types of DDoS attacks and emphasizes detection approaches. The standout approach and one that can answer the complexity of detecting DDoS attacks is the classification with artificial intelligence techniques. This work shows why artificial intelligence represents the starting point for further research in information security.International Scientific Conference "Archibald Reiss Days", Belgrade, 18-19 November 202
A Multicriteria Decision Aid-Based Model for Measuring the Efficiency of Business-Friendly Cities
No full textLocal self-government has the task of enabling stable economic development, in addition to enabling a normal quality of life for citizens. This is why the state government should provide guidelines that will improve the local business climate, and by doing so enable local economic development. This can be done through the introduction of a business-friendly certification procedure, which is influenced by uncertain inputs and influences many output factors. Each local government has the important task of determining its rank of efficiency in this process. A number of methodologies developed to solve this problem are generally divided into two groups: Parametric and non-parametric. These two groups of methodologies could provide quite different results. Therefore, the purpose of this paper was to create a model using both approaches to achieve a balanced symmetrical approach that produces better results than each approach individually. For this purpose, the paper describes a multicriteria decision aid-based model of optimization to evaluate the effectiveness of this process, integrating classification, data envelopment analysis, and stochastic frontier analysis, as well as its application in a case study of business-friendly certification in the Republic of Serbia

Get PDFDokazni značaj fotografije u kriminalističkim istragama
No full textPhotography is admitted as one of the widely used methods in criminal
investigation which has a significant evidentiary potential, but only if it is
made according to special technical and procedural rules. Considering its
great value in the collecting and examination of material evidences, in
this paper it will be presented the review of application of photography in
the process of proving the facts in criminal proceedings. At first, it will be
presented the general legal rules on the manner of proving and assessment
of the evidence in criminal proceedings, which are decisive in considering
photography as evidence. The focus will be on photographs which are used or
obtained by conducting evidentiary actions, such as witnesses’ identification
and covert surveillance and audio and video recording and photographs
which represent technical contribution to other evidentiary actions, such as
crime scene investigation. Finally, it will be considered evidentiary action
named proving by a record, under which the use of photography as evidence
could be subsumed, with reference to relevant cases from the case law in
Republic of Serbia.Fotografija je prihvaćena kao jedna od zastupljenijih metoda

Sociodemographic Characteristics of the Homicidal Population
Get PDFИмајући у виду да убиство представља
најтежи облик криминалне активности, чија је
распрострањеност нажалост постала социјални проблем од
огромног значаја, циљ овог истраживања био је да у садашњим
друштвеним околностима идентификујемо социодемографске
карактеристике хомицидалне популације, која се тренутно
налази на издржавању казне затвора у највећим казненопоправним заводима на територији Србије. Истраживање је
спроведено током 2019. године и обухватило је 138 осуђеника
мушког пола старости 24–78 година, који су издржавали казну
затвора у казнено-поправним заводима у Нишу, Пожаревцу,
Падинској скели и Сремској Митровици због извршених кривичних
дела убиства из члана 113 и тешког убиства из члана 114 КЗС.
Резултати истраживања показују да је највећи број убица
старости од 31 до 40 година, као и да су рођени односно имају
пребивалиште у градским срединама. У погледу радног и
социјалног статуса, резултати показују да су убице у највећем
проценту особе са завршеном средњом школом, да су пре издржавања казне затвора били запослени на неодређено време,
да су по занимању занатлије и техничари разних струка, да су
неожењени, као и да су средњег социоекономског статуса. У
погледу криминалне активности, највећи проценат убица је
раније био осуђиван због имовинских и насилних деликата.The criminal act of murder is considered to be one
of the more serious criminal offenses, since the person is deprived of
the basic and most important right, and that is the right to life.
Psychologists have always shown a great interest in this kind of violent
delicts, as well as interpersonal violence in general. Attempting to
explain and understand this type of violent behavior, they proceeded,
most often, with studying the personality interaction and its sociopsychological environment. On the other hand, by studying the most
important modalities of sociodemographic features, in our work, we
tried to determine them from an etiological side, the bearers of this
criminal activity more precisely, keeping in mind that murder is one of
the most difficult forms of interpersonal violence, which is,
unfortunately, a part of our everyday lives.
The sample included 138 male prisoners aged 24-78 who were
serving a prison sentence in Penitentiary Rehabilitation Institutions in
Niš, Požarevac, Padinska skela, and Sremska Mitrovica, due to the
crimes and killings they had committed. Respondents completed a
questionnaire made for research purposes, which collects general
sociodemographic data, as well as data related to earlier criminal
activity. The results have shown that the majority of killers belong to
the age structure of 31 to 40 years and that they were born or have had
a place of residence in urban areas. The structure, in terms of social
and working status, was diverse, starting from unskilled workers,
workers without interest, craftsmen, and technicians of various
professions, to private entrepreneurs, engineers, etc.
In terms of other sociodemographic characteristics, the results of
the survey have shown that they were convicted persons who had
completed high school in the largest percentage, that they had been
employed before serving the prison sentence, and that they were of a
medium socioeconomic status, with about half of the respondents
saying that they had incomes higher than the average net salary in
Serbia. Regarding criminal activity, the highest percentage of killers
had previously been convicted for crimes committed in the field of
property delicts, including robbery, as well as violent delicts, including
murder.
In an attempt to derive some general conclusions on the
phenomenological features of homicide, based on sociodemographic
characteristics, we are brought back to one of the previously
mentioned statements about the significance of psychological and
situational factors in the manifestation of criminal behavior. Namely,
the ones including age, education, employment, occupation, marital
status, economic circumstances. The nature of the place of birth and
place of residence can hardly be considered as reliable indicators of
an increased risk for participation in the criminal activities of the
homicidal population. Nevertheless, this, and other empirical research
support the fact that the killers are a heterogeneous population, in a
phenomenological sense, with respect to demographic characteristics,
and that social features are only the breaking point of several
etiological factors
