Evaluation of Positive Socio-Economic Phenomena in Territorial Systems of Ecological Stability (Case Study)

One of the active tools that increase the ecological stability of a country are projects related to territorial systems of ecological stability (TSES). An important part of the elaboration of TSES projects is also the evaluation of positive socio-economic phenomena (PSEP). Their evaluation is important for the design of measures that will ensure its proper functioning. The PSEP enter, the spatial system as elements that fulfill important ecological functions and help preserve the natural resources, gene pool, ecological stability and diversity of the landscape. Therefore, it is necessary to maintain their functions in the future. The theoretical and methodological basis for the evaluation of PSEP within TSES is the LANDEP methodology. They are not unique in the area, and they can occur in various combinations. Based on varied combinations of positive phenomena ensuing from nature conservation, protection of water sources, forest and soil sources, mineral resources and cultural or historical resources there are various types of territories with different landscape ecological significance and different ecological stability. The resulting combinations are a limiting input for the proposed activities and must be respected when processing ecostabilization measures within TSES projects. The presented study presents a landscape ecological evaluation of socio-economic phenomena of nature protection and natural resources in a project of the local system of ecological stability which was developed for the agriculturally intensively used area of Dolný Lopašov. It assesses the legal status of the territory and specifies and spatially expresses areas with different representations of important landscape elements which come under legislative protection. Based on the occurrence, abundance, character and combinations of PSEP occurring in the cadastral area of the commune Dolný Lopašov, this specifies 8 degrees of landscape ecological significance. Significance categories form the basis for the overall classification of the territory required for the processing of TSES projects at the local level. The obtained results must be applied to the proposals of measures to increase ecological stability, especially in the central and southern part of the cadastral area of the commune Dolný Lopašov.

A comparative study using supervised learning for anomaly detection in network traffic

A user connects to hundreds of remote networks daily, some of which can be corrupted by malicious sources. To overcome this problem, a variety of Network Intrusion Detection systems are built, which aim to detect harmful networks before they establish a connection with the user’s local system. This paper focuses on proposing a model for Anomaly based Network Intrusion Detection systems (NIDS), by performing comparisons of various Supervised Learning Algorithms on metric of their accuracy. Two datasets were used and analysed, each having different properties in terms of the volume of data they contain and their use cases. Feature engineering was done to retrieve the most optimum features of both the datasets and only the top 25% best features were used to build the models – a smaller subset of features not only aids in decreasing the capital required to collect the data but also gets rid of redundant and noisy information. Two different splicing methods were used to train the data and each method showed different trends on the ML models.

Trends of Power Devolution in South Asia: A Comparative Appraisal of Pakistan’s Local Government System under the Civil-Military Regimes

In the South Asian countries, the trends of power sharing, decentralization and power evolution have not only always remained a pertinent debate for the consolidation of democracy and good governance, but also static political systems due to their multiethnic realities, multilingual differences, multicultural diversification, and their authoritarian orientation in the respective countries. Historically, the transfer of power through the local system of government (LGS) was seen as an important tool to accelerate the transition to representative democracy on the subcontinent. However, it was largely aimed at creating a new political class that would support colonial rule and meet the political demands of the local population for power sharing within the boundaries of the colonial government structure. Due to their embedded interests, the colonial legacies in South Asian states offered non-representative state institutions such as the military enough space to influence the transformation process of democracy. The paper has two main objectives: (1) to explore the concepts of power devolution and their associative nomenclature; (2) to analysis of the political and administrative dimensions of decentralization to underpin the structure of decentralization in South Asia in general and Pakistan in particular. The results of the study are that the lack of the weakest local government system in the South Asian region in general, and in Pakistan in particular, is due to the colonial legacy of an ongoing controlled political mindset in the form of bureaucracy, frequent military coups, a lack of political will to develop a welfare state in Pakistan. It uses the qualitative research methods of phenomenology and correlation, which sheds light on the meaning of relative terms often used to explain delegation of authority for political and administrative purposes.

Ensuring power balance in a hybrid power system with a standby generator

The combination of several non-guaranteed random energy sources (RES), conventional sources, and nonconstant consumer loads in a local system leads to stochastic power imbalances. This study objective consists in determining the possibilities of ensuring the power balance in a hybrid power generation system with a standby generator and a search for the methods of calculating the optimal parameters to achieve energy balance. This objective is achieved by simulating the processes inherent in wind and solar power engineering and the regimes of energy consumption through a combination of random functions with a standard probability distribution. Aggregated data on weather factors for several years in a region with a high renewable energy potential which can be used to describe the behavior of wind and solar energy over time were used as experimental data. The use of multiple simulations of random processes with calculated parameters has made it possible to draw conclusions about the presence of certain ratios of power and the generator control modes. These ratios can determine minimum energy and consumption losses, reduce the likelihood of energy imbalance, more efficiently use the reserved power. Specific features of the stochastic nature of RES related to the presence of trends and random fluctuations at short hourly intervals were additionally taken into account. Possibilities of varying the conditions of and switching on and off of the standby generator were provided. The existence of some ranges was established for the installed power of the generator outside which its use becomes inefficient. The proposed approach makes it possible to find the probability of various system states, assess the reliability of energy supply, and minimize unproductive losses.

Time-domain numerical modeling of wave propagation in poroelastic media with rational approximation of the fractional attenuation

n this work, we investigate the poroelastic waves by solving the time-domain Biot-JKD equation with an efficient numerical method. The viscous dissipation occurring in the pores depends on the square root of the frequency and is described by the Johnson-Koplik-Dashen (JKD) dynamic tortuosity/permeability model. The temporal convolutions of order 1/2 shifted fractional derivatives are involved in the time-domain Biot-JKD model, causing the problem to be stiff and challenging to be implemented numerically. Based on the best relative approximation of the square-root function, we design an efficient algorithm to approximate and localize the convolution kernel by introducing a finite number of auxiliary variables that satisfy a local system of ordinary differential equations. The imperfect hydraulic contact condition is used to describe the interface boundary conditions and the Runge-Kutta discontinuous Galerkin (RKDG) method together with the splitting method is applied to compute the numerical solutions. Several numerical examples are presented to show the accuracy and efficiency of our approach.

An Experimental Implementation of a Resilient Graphic Rendering Cluster

In this paper, we describe the challenge of developing a web front that will give an interactive and relatively immediate result without the overhead of complex grid scheduling, in the sense of the grid’s lack of interactivity and need for certificates that users simply do not own. In particular, the local system of issuing grid certificates is somewhat limited to a narrower community compared to that which we wanted to reach in order to popularize the grid, and our desired level of service availability exceeded the use of the cluster for grid purposes. Therefore, we have developed an interactive, scalable web front and back-end animation rendering frame dispatcher to access our cluster’s rendering power with low latency, low overhead and low performance penalty added to the cost of Persistence of Vision Ray rendering. The system is designed to survive temporary or catastrophic failures such as temporary power loss, load shedding, malfunction of rendering server cluster or client hardware, whether through an automatic or a manual restart, as long as the hardware that keeps the previous work and periodically dumped state of the automata is preserved.

FUJITA DECOMPOSITION AND MASSEY PRODUCT FOR FIBERED VARIETIES

Let $f\colon X\to B$ be a semistable fibration where X is a smooth variety of dimension $n\geq 2$ and B is a smooth curve. We give the structure theorem for the local system of the relative $1$ -forms and of the relative top forms. This gives a neat interpretation of the second Fujita decomposition of $f_*\omega _{X/B}$ . We apply our interpretation to show the existence, up to base change, of higher irrational pencils and on the finiteness of the associated monodromy representations under natural Castelnuovo-type hypothesis on local subsystems. Finally, we give a criterion to have that X is not of Albanese general type if $B=\mathbb {P}^1$ .

Volunteering in the time of COVID-19. The Polish example for Europe

The subject of the article is the analysis of the possibilities of using the volunteering to counteract adverse effects of crisis situation based on the example of the coronavirus pandemic. The authors examine the Solidarity Corps for Seniors’ Support (pl. Solidarnościowy Korpus Wsparcia Seniorów) and the local system Warsaw Supports ( pl. system Warszawa Wspiera) applying the institutional and normative method, and case study method in an attempt to provide answers to the following questions: (1) How and under what rules was the volunteering potential used to support the citizens? (2) Did the actions based on volunteer activity undertaken in Poland efficiently complement the work of public authorities? (3) Is the implementation of the developed solutions and their usage within the European Solidarity Corps structure possible in similar cases in the future? The case study allows to conclude that Polish solutions proved to be efficient and allowed to formulate the proposals of establishing a broader cooperation between the EU Member States concerning experience sharing in voluntary work development in crisis situations.

The question of determining installation sites for the Air purification of pig premises local system elements

The allocation of intake air stream in pig premises is not evenly. The existence of engineer-ing networks and equipment, the breaching of montage technologies of air ventilation, incorrect maintenance of air ventilation system – all these factors bring to many breaches and problems. This problem such as air exchange violation in all premises, appearing zones of stasis (aero stasis), and others. As a result of which the differential of temperature and humidity has appeared. These also appear excess maximum per-mitted concentration of dust and gases. The all-exchanged ven-tilation system can’t solve all problems in local zones in pig premises. In this local air-ventilation system become more demand. For effective work of local air ventilation, the question of deter-mining installation sites for the air purification of pig premises local system elements should be solved.

Development of a Southern Vilnius Standard Photometric System

<p>The Vilnius Standard Photometric System is said to have several advantages over other photometric systems; reduction procedures free of systematic errors, a homogeneous set of standard stars, accurate dereddening, spectral classification and calibration of physical parameters for normal stars, and a good detection rate of abnormal stars. To investigate these, two southern, open star clusters (Omicron Velorum and Kappa Crucis) have been measured in the Vilnius system. The observations were used to derive astrophysical parameters such as age ((45 plus-minus l5)x106 and (10 plus-minus 3)x10 6 years respectively), composition (both solar metallicity), distance to the clusters (m-M = 5m.94 plus-minus 0.02 and 12m.18 plus-minus 0.05), interstellar reddening along our light of sight to the clusters (Ey-v = 0m.00 plus-minus 0.02 and 0m.31 plus-minus 0.09), and cluster membership probabilities for the individual stars. These compared favorably with the consensus of similar analyses made by observers using other photometric systems, with one exception being the distance to Kappa Crucis ( = 11m.59). As no stars further south than declination -26 degrees have been measured in the (original) Vilnius System, it was necessary to calibrate the local system to the standard system by measuring equatorial stars common to both. To alleviate this problem in the future, suitable southern stars were measured to form a southern standard system. Initially bright stars evenly spread across the sky were calibrated - this will ensure any future observing programme will have nearby standards. The next phase of the programme was to calibrate the E-region stars - this is a set of stars in common use as southern standards in other photometric systems. The final phase was to calibrate a sequence of stars near the south celestial pole - producing a set of stars so that the same standards can be observed at any time during the year. This southern standard system could not be completely established in the time available (it is approximately 50% finished), due to the larger than expected uncertainties in the measurements largely caused by the atmospheric effects of the Mount Pinatubo eruption.</p>
