Abstract:

Meta-evaluations by Quality Assurance Agencies (QAAs) aim to evaluate the quality of the evaluators of quality assurance. While such evaluations are the norm, especially in Europe, they are rare in Africa. A critical literaturereview was conducted to ascertain whether meta-evaluations were conducted in Namibia. The study estab- -lished that such evaluations have yet to be practiced in the country. Drawing on Clark’s model of the organisa- -tional analysis of higher education institutions and the higher education system as an analytical lens, and based on the African Standards and Guidelines for Quality Assurance and some cases of meta-evaluation byQAAs, we argue for the need to conduct such evaluations in Namibia. The article provides an overview of QAAs’ operations and functions, as well as the current external quality assurance system for higher education inNamibia and justifies the necessity of meta-evaluation in the Namibian context in order to enhance the capacity of QAAs and the quality of higher education institutions. Key words: Higher Education, meta-evaluation, Namibia, quality assurance, Quality Assurance Agencies

Abstract:

Eternal domination of a graph requires the vertices of the graph to be protected, against infinitely long sequences of attacks, by guards located at vertices, with the requirement that the configuration of guards induces a dominating set at all times. Klostermeyer and Mynhardt studied some variations of this concept in which the configuration of guards induces total dominating sets (TDSs). They considered two models of the problem, one in which only one guard moves at a time and one in which more than one guard may move simultaneously. In this paper, we consider the model in which all guards move simultaneously when the configuration of guards induces TDSs and we study this model for some classes of graphs.

Abstract:

With the increase of mining height, the problem of coal wall spalling in the working face gradually worsens. Hydraulic support and its face guard structure are the key pieces of equipment to restrain the coal wall spalling. However, at present, the hydraulic jack is mostly considered as rigid in the analysis of protection mechanism. This simplification cannot effectively reflect the true bearing state of the face guard. In order to improve the accuracy of analysis, this study considers the face guard jack as a flexible spring and establishes a rigid-flexible coupling analysis model of the face guard mechanism. First, based upon the multibody dynamics software ADAMS®, the multibody numerical model of the face guard of the hydraulic support was established. The influence of the two kinds of structures on the coal wall disturbance was analyzed and compared. Then, the rigid model was meshed. The hydraulic jacks were equivalent to the spring system, and the rigid-flexible coupling model was established. Based upon the application load on different positions of the rigid-flexible model, the load-bearing characteristics and hinge point force transfer characteristics of the two face guards were analyzed. The results show that the support efficiency of the integral type was higher than that of the split type. In the vertical support attitude, the dynamic disturbance of the coal wall, produced by the two kinds of face guards, was small. The four-bar linkage effectively improved the ultimate bearing capacity of the integral face guard. The results provide theoretical support for the design and optimization of the face guard.

Abstract:

An eternal dominating set of a graph G is a set of guards distributed on the vertices of a dominating set so that each vertex can be occupied by one guard only. These guards can defend any infinite series of attacks, an attack is defended by moving one guard along an edge from its position to the attacked vertex. We consider the “all guards move” of the eternal dominating set problem, in which one guard has to move to the attacked vertex, and all the remaining guards are allowed to move to an adjacent vertex or stay in their current positions after each attack in order to form a dominating set on the graph and at each step can be moved after each attack. The “all guards move model” is called the m -eternal domination model. The size of the smallest m -eternal dominating set is called the m -eternal domination number and is denoted by γ m ∞ G . In this paper, we find the domination number of Jahangir graph J s , m for s ≡ 1 , 2 mod 3 , and the m -eternal domination numbers of J s , m for s , m are arbitraries.

Abstract:

The goal of this study was to evaluate the effectiveness of a number of shin guards in protecting against tibia fracture in soccer players. A secondary purpose was to determine the relationship between the material and structural differences in shin guard design and the protection provided. Twenty-three commercially available shin guards were tested on a model leg containing a synthetic tibia that had been calibrated against human cadaver specimens. Each guard was categorized into one of four material types: plastic (N 9), fiberglass (N 6), compressed air (N 4), and Kevlar (N 4). The maximum combined force at the ends of the tibia, the principal strain on the posterior side of the tibia, and the contact time of the impact were measured using a drop track impact simulation. Shin guards provided significant protection from tibia fracture at all drop heights. The average guard reduced force by 11% to 17% and strain by 45% to 51% compared with the unguarded leg. At the higher drop heights, material composition and structural characteristics of the shin guards showed significant differences in protective abilities. These findings indicate that all shin guards provide some measure of protection against tibia fracture, although the level of protection may vary significantly among the different guards.

Abstract:

The work is devoted to the issue of the complex use of technical means and physical security forces while ensuring the safety of several objects located in the controlled area. The method proposed is for solving the problem of choosing a strategy for searching for a criminal by a security officer while minimizing the time of knowing the direction of movement of the first one to one of the two objects. The proposed method is based on a criminal search strategy implemented by the security guards movement control system, which includes two straight sections of their path, which are formed based on information from the security alarm sensors. A mathematical model has been developed for calculating the parameters of controlling the movements of a guard and an algorithm for the control system operation, which makes it possible to implement an optimal search strategy depending on the location of objects, a guard, a criminal, and information from technical means of protection.

Abstract:

Dynamic Guard Channels (DCG) reduces the dropping and blocking rates in a network. However, most of the existing DGC allocations are not quite efficient because there were consideration for only the Handoff (HO) calls while the New calls (NC) were not considered; this leads to poor Quality of Service (QoS) for NC. Although it is better to give priority to HO calls over NC since the breaking of the connection of an established communicationis more annoying than blocking a NC. Thus, there is need to provide an alternative approach that guarantees an acceptable QoS in terms of both the HC and the NC. This paper presents the performance evaluation of an adaptive guard channel allocation; the scheme made use of two different models (1) guard channel with fuzzy logic (2) guard channel without fuzzy logic. Priority is given to handoff call due to the scarcity of radio spectrum. When all the guard channels have been allocated and the arrival rate of handoff calls keeps on increasing, new set of threshold values would be estimated by fuzzy logic model. Performance metrics are; Call Blocking Rate (CBR), Call Dropping Rate (CDR) and Throughput. Results showed that guard channel with fuzzy logic has the CBR values range from 24.02% to 69.015 and CDR values range from 12.025 to 18.90% while guard channel without fuzzy logic has CBR values range from 28.22% to 75.65% and CDR values range from 19.06% to 36.50%. The scheme proved to be more efficient in congestion control in wireless network.

Abstract:

Employee performance appraisal is a work evaluation activity that is used to determine the quality which will be used for the achievement of each individual employee. The purpose of this research is to appraise employee performance, especially for the security guard. In this study the authors used the Decision Support System technique using the Fuzzy Multi Attribute Decision Making algorithm, namely Weighted Product. The source of the research data used was to provide an assessment form to Krani Papam. In the employee performance appraisal, researchers used 5 assessment criteria, including: Attendance (C1), Responsibility (C2), Commitment (C3), Cooperation (C4), and Motivation (C5). In this study, the alternative used as a sample is employees in the security section (security guard). From the results of manual calculations and system testing, the highest value is 0.0286. It is expected that the results of this study can provide input to the office, especially the security section (security guard) in selecting employee performance so that the assessment is carried out objectively.

Abstract:

Powerful n-channel DMOS-transistor with drain-source breakdown voltage Uds br value over 800 V and thresh-old voltage from 2 to 5 V was considered in this paper. One or more guard rings are formed on perimeter of such transistor for the breakdown voltage raising. The optimal guard rings construction was described and resistivity value of epitaxial film ρv was determined for obtaining required transistor Uds br value. The regression model was built, with the help of which the most optimal construction variants of guard rings of investigated transistor and resistivity value of epitaxial film, were selected. It was established that the five-dimensional polynomial of second order using as regression model allowed choosing the optimal topological spaces values in the guard rings area and ρv value which made it possible to obtain required Uds br values of the transistor. Experimental values of transistor drain-source breakdown voltage were 876 and 875 V, but calculated values (at identical parameters of definitional regression model) were 874 and 880 V, accordingly, that were errors of 0.23 % and 0.57 %, i. e. made model fits well with experimental data. It was established that ρv makes contribution to breakdown voltages values of the transistor that is more substantial than parameters of guard rings construction. This NDMOS-transistor was manufactured under production conditions of OJSC INTEGRAL” – “INTEGRAL” Holding Managing Company according to the technological route developed by the author. Such device is used in various electronic devices for energetics, in mobile phones, as part of high-voltage integrated circuits of AC/DC- and DC/DC-converters and high-voltage, high-stable LED-drivers.

Abstract:

AbstractThe history of humanity got from the Persians the first imperial organization, the first process of integration of the conquered ones, the first postal service, the most effective means of communication at the dawn of Antiquity, and also the best organized militarized services.The most special of the Indo-European Antiquity troops was the Royal Guard, founded by Darius I, one of the great kings of humanity, a political titan, and equally an extraordinary general through his institutional creations of force. The Royal Guard of Darius I, known in history as the 10,000 immortals, is the subject of our study, as it is one of the most complex special militarized structures in human history of all time, inspiring the military structures of all the Indo-Europeans, whether the Hoplite revolution, the organization of the Macedonian phalanx or the Roman Praetorian Guard and more than that.The 10,000 immortals combined not only the heroic character (while multiplying it), which appeared for the first time with the Greeks of the Homeric period, but also strict discipline, in the Spartan sense, contemporary with this troop, the organization and the well-developed logistics, which would inspire the Roman army, the military brotherhoods characteristic of all the Indo-Europeans, but this totally special troop, in particular, imposed the model of the educated (even intellectual) military man, a soldier of the supreme god of the Good, faithful first of all to the Good and to his king, a military man who used all the weapons of the time.This special troop was a true institution that also provided information to the Persian king, information being one of the most effective weapons. Moreover, the Persians through this Royal Guard used for the first time psychological impact as a weapon, this being the first case of effective manipulation by the number that was kept constant, but also by name. Only the gods were immortal, and the very large number of soldiers who made up this special troop is impressive even today. The armament of this extraordinary troop comprised all the weapons of the time, the bow above all, which the Aryans considered the favourite weapon of Indra, the most warlike god of the Indo-European gods.

Abstract:

Despite the use of wrist guards during skate- and snowboard activities, fractures still occur at the wrist or at further proximal locations of the forearm. The main objectives of this study were to conduct a human subject testing under simulated falling conditions for measurement of the impact force on the hand, to model wrist guards as a shock isolator, to construct a linear mass-spring-damper model for quantification of the impact force attenuation (Q-ratio) and energy absorption (S-ratio), and to determine whether wrist guards play a role of an efficient shock isolator. While the falling direction (forward and backward) significantly influenced the impact responses, use of wrist guards provided minimal improvements in the Q- and S-ratios. It was suggested based on the results under the submaximal loading conditions that protective functions of the common wrist guard design could be enhanced with substantial increase in the damping ratio so as to maximize the energy absorption. This would bring forth minor deterioration in the impact force attenuation but significant increase in the energy absorption by 19%, which would help better protection against fall-related injuries of the upper extremity.

Abstract:

Since the first recordings of single potassium channel activities in the plasma membrane of guard cells more than 25 years ago, patch-clamp studies discovered a variety of ion channels in all cell types and plant species under inspection. Their properties differed in a cell type- and cell membrane-dependent manner. Guard cells, for which the existence of plant potassium channels was initially documented, advanced to a versatile model system for studying plant ion channel structure, function, and physiology. Interestingly, one of the first identified potassium-channel genes encoding the Shaker-type channel KAT1 was shown to be highly expressed in guard cells. KAT1-type channels from Arabidopsis thaliana and its homologs from other species were found to encode the K+-selective inward rectifiers that had already been recorded in early patch-clamp studies with guard cells. Within the genome era, additional Arabidopsis Shaker-type channels appeared. All nine members of the Arabidopsis Shaker family are localized at the plasma membrane, where they either operate as inward rectifiers, outward rectifiers, weak voltage-dependent channels, or electrically silent, but modulatory subunits. The vacuole membrane, in contrast, harbors a set of two-pore K+ channels. Just very recently, two plant anion channel families of the SLAC/SLAH and ALMT/QUAC type were identified. SLAC1/SLAH3 and QUAC1 are expressed in guard cells and mediate Slow- and Rapid-type anion currents, respectively, that are involved in volume and turgor regulation. Anion channels in guard cells and other plant cells are key targets within often complex signaling networks. Here, the present knowledge is reviewed for the plant ion channel biology. Special emphasis is drawn to the molecular mechanisms of channel regulation, in the context of model systems and in the light of evolution.

Abstract:

Stomatal pore apertures are narrowing globally due to the continuing rise in atmospheric [CO2]. CO2 elevation and the plant hormone abscisic acid (ABA) both induce rapid stomatal closure. However, the underlying signal transduction mechanisms for CO2/ABA interaction remain unclear. Two models have been considered: (i) CO2 elevation enhances ABA concentrations and/or early ABA signaling in guard cells to induce stomatal closure and (ii) CO2 signaling merges with ABA at OST1/SnRK2.6 protein kinase activation. Here we use genetics, ABA-reporter imaging, stomatal conductance, patch clamp, and biochemical analyses to investigate these models. The strong ABA biosynthesis mutants nced3/nced5 and aba2-1 remain responsive to CO2 elevation. Rapid CO2-triggered stomatal closure in PYR/RCAR ABA receptor quadruple and hextuple mutants is not disrupted but delayed. Time-resolved ABA concentration monitoring in guard cells using a FRET-based ABA-reporter, ABAleon2.15, and ABA reporter gene assays suggest that CO2 elevation does not trigger [ABA] increases in guard cells, in contrast to control ABA exposures. Moreover, CO2 activates guard cell S-type anion channels in nced3/nced5 and ABA receptor hextuple mutants. Unexpectedly, in-gel protein kinase assays show that unlike ABA, elevated CO2 does not activate OST1/SnRK2 kinases in guard cells. The present study points to a model in which rapid CO2 signal transduction leading to stomatal closure occurs via an ABA-independent pathway downstream of OST1/SnRK2.6. Basal ABA signaling and OST1/SnRK2 activity are required to facilitate the stomatal response to elevated CO2. These findings provide insights into the interaction between CO2/ABA signal transduction in light of the continuing rise in atmospheric [CO2].

Abstract:

Guard cells are now recognized as the premier cell model in plants. Much of this notoriety can be traced to research over the previous three decades into the signalling mechanisms behind abscisic acid (ABA), its ability to regulate ion transport across the plasma and vacuolar membranes of guard cells, and thereby to drive stomatal movements. Guard cells surround stomatal pores of plant leaves. They control the aperture of the pore and, so, CO2 entry into the leaf for photosynthesis and water loss via transpiration. Their sensitivity to environmental and endogenous stimuli makes them ideal for physiological studies, and their situation makes them well-suited for cellular and subcellular research. The ‘read-out’ of stomatal aperture is also central to the crisis in water availability and crop production that is expected to unfold over the next 20–30 years. Not surprisingly, there is growing interest in ‘reverse engineering’ stomatal guard cells to improve agricultural water use. It seems like an openand-shut case. But is it?

Such an agreement between a federal agency and an Indian tribe is authorized by Executive Order 13175 - Consultation and Coordination with Indian Tribal Governments, signed in 2000 and is consistent with the 2011 Department of Homeland Security Tribal Consultation Policy. This groundbreaking document represents a 20 year relationship between key members of the Makah Tribe and the oil spill response members of CG D13 and Sector Puget Sound, and the trust developed over that period while working together to mutually support each party's oil spill prevention, preparedness and response readiness, as well as the desire to help and support each other by harmonizing efforts. With recent legislation such as the 2010 Coast Guard Authorization act, authorizing resources to engage tribes into training, exercises and other spill response preparedness activities particularly in the Northwest, it became clear there was a need to memorialize the strong supportive working relationship between the Makah and the CG, and provide some structure to our planning and development efforts. The MOA lays out a minimum of semi-annual meetings during which the two parties discuss overarching items of mutual interest and determine a work list of concrete, achievable goals to complete within the next 6 month period. An initial work list of common interest issues and responsibilities are outlined in the MOA, and fall into three general categories: Prevention; Preparedness and Response. The MOA also addresses the importance of Communication with the goal of enhancing mutual situational awareness via improved communication protocols between the Coast Guard and the Makah Tribe.

Abstract:

An important property of intelligent virtual agents (IVAs) and multiintelligent virtual agents systems (mIVAS) is their capability to acquire/perceive information from their environment. In this paper we present an auditory perceptual model for IVAs and mIVAS, which extends and reinterprets the key concepts of one of the awareness models developed for computer supported cooperative work (CSCW) applications, the spatial model of interaction (SMI). This perceptual model also introduces some factors typical of human perception—such as auditory acuity—as well as others associated with the sound source and its propagation with the aim of making perception in this kind of system more humanlike.

Abstract:

Hardware-in-the-Loop (HIL) simulation technique is implemented to analyze the performance characteristics of an energy dissipative under-ride guard system for enhancement of crashworthiness of lightweight vehicles involved in coillisions with heavy freight vehicles. The experimental setup, software and hardware interface, and the test methodology used to perform the HIL simulation are briefly described. The energy dissipating under-ride guard, while impacted by a car body, is analytically modeled incorporating nonlinearities due to asymmetric damping in compression and rebound, restoring properties and kinematics of linkages, using the principles of conservation of momentum and Lagrangian dynamics. The performance characteristics of the under-ride guard are evaluated under direct impact at different speeds, and the results obtained from the HIL simulation are compared with those derived from the nonlinear analytical model. The study revealed very good correlation between the analytical and experimental findings in terms of the amount of energy dissipated, acceleration level, rebound velocity and the magnitude of intrusion. An analysis of the results showed that significant portion of the kinetic energy can be dissipated by the under-ride guard.

Abstract:

It is held the analysis of the state of functioning of the system of technical support of automobiles and armored vehicles factory parks. The basis of this system is the technical support units. These units provide quality and timely implementation of technical influences on machinery. So, the main task of information support of technical support is to determine the needs of vehicles parks in such influences and an assessment of the capabilities of the relevant technical support units. Thus, there is an urgent need to model the functioning of these units. These units can be internal or external, with which the Internal Subdivision is subordinate to the State Border Guard Service of Ukraine and the external unit is subordinate to another organization. All these types of units need to be analyzed. The end result of the functioning of this system is the implementation of such a managerial influence on its structure, which will provide maximum effect of the adaptation of the combined system of technical support of automobile and armored vehicles fleets of the units of the State Border Guard Service of Ukraine. Thus, successful resolution of the tasks of information support of technical support of automobile and armored vehicles fleets of the units of the State Border Guard Service of Ukraine requires formalization of the functioning of certain technical support units. The study simulates this process. The technical support unit is presented as a mass service system with an extraordinary inbound request flow and a limited service queue. As a result, a number of dependencies were obtained that allow forecasting of the possibilities of separate technical support departments of technical parks and use of the obtained values in the process of implementation of the information support of technical support of such parks. Keywords: technical support system, technical support unit, model, mass service system, efficiency.

Abstract:

An animal model that allows for assessment of the degree of stretching or contraction of the implant area and the in vivo degradation properties of biological meshes is required to evaluate their performance in vivo. Adult New Zealand rabbits underwent full thickness subtotal unilateral rectus abdominis muscle excision and were reconstructed with the non-biodegradable Peri-Guard®, Prolene® or biodegradable Surgisis® meshes. Following 8 weeks of recovery, the anterior abdominal wall tissue samples were collected for measurement of the implant dimensions. The Peri-Guard and Prolene meshes showed a slight and obvious shrinkage, respectively, whereas the Surgisis mesh showed stretching, resulting in hernia formation. Surgisis meshes showed in vivo biodegradation and increased collagen formation. This surgical rabbit model for abdominal wall defects is advantageous for evaluating the in vivo behaviour of surgical meshes. Implant area stretching and shrinkage were detected corresponding to mesh properties, and histological analysis and stereological methods supported these findings.

Abstract:

Исследуется структурно-функциональная модель развития готовности специалистов защиты информации к профессиональной деятельности в войсках национальной гвардии Российской Федерации. Выделенные компоненты (нормативно-концептуальный, программно-целевой, профессионально-деятельностный и контрольно-оценочный) позволят развить необходимый уровень, который будет достаточен для совершения профессиональной деятельности в Росгвардии. Методологическую основу разработанной модели составляет компетентностный и системно-деятельностный подходы, позволяющие раскрыть концептуально-ориентирующую функцию процесса обучения будущих специалистов защиты информации. Применение системно-деятельностного подхода в структурно-функциональной модели развития готовности понимается как новое выражение деятельностного подхода, который в настоящее время вызывает большой интерес у большинства ученых и исследователей. Проведенный анализ отзывов, поступающих от командиров воинских частей Росгвардии на выпускников факультета (связи) Пермского военного института войск национальной гвардии, показал необходимость при организации учебного процесса более углубленно рассматривать вопросы обеспечения защиты информации, проведения необходимых мероприятий по аттестации выделенных помещений, развития практической составляющей по отражению хакерских и иных атак на информационное пространство Росгвардии. Основу технологии обучения специалистов защиты информации к профессиональной деятельности составляет реализация специализированного курса проведения «Киберучений», включающего в себя комплекс практических и лабораторных работ. Разработанные в этом же специализированном курсе ситуационные задачи, составленные по основам собственного опыта в обеспечении защиты информации в качестве контролирующего органа, позволят будущим специалистам защиты информации при организации проверок защищенности объектов не допускать шаблонных ошибок и корректировать свою профессиональную деятельность. The article examines a structural-functional model of the development of readiness to develop the readiness of information security specialists for professional activity in the troops of the National Guard of the Russian Federation. The highlighted components: normative-conceptual, program-target, professional-activity and control-assessment will allow developing the necessary level that will be sufficient for performing professional activities in the Russian Guard. The methodological basis of the developed model is the competence-based and system-activity approaches, which allow the conceptual-orienting function of the training process of future information security specialists. The use of the system-activity approach in the structural-functional model of readiness development is understood as a new expression of the activity approach, which is currently of great interest to most scientists and researchers. The analysis of the reviews received from the commanders of the military units of the Russian Guard on the graduates of the faculty (communications) of the Perm Military Institute of the National Guard troops showed the need, when organizing the educational process, to consider in more depth the issues of ensuring the protection of information, taking the necessary measures to certify the allocated premises, developing a practical component to repel hacker and other attacks on the information space of the National Guard. The basis of the technology for training information security specialists for professional activities is the implementation of a specialized course for conducting «Cyber training», which includes a set of practical and laboratory work. The situational tasks developed in the same specialized course, compiled on the basis of their own experience in ensuring the protection of information as a supervisory authority, will allow future information security specialists to avoid stereotyped errors when organizing security checks of objects and adjust their professional activities.

Abstract:

The 2Dwhitenoise model has been extended to represent a modified power law that is realistic. It allows for finite moments for the interference.The white noise processes with a decaying power law.Impulse response functions are ideally suited for modeling the network self-interference in an ad hoc network.The nodes are distributed in a plane according to a Poisson point process. A stochastic impulse response function is used to model different random parameters like channel fluctuation, variable transmission power of the nodes etc. For a decaying power law, all the moments of the interference diverge.We have presented performance curves for the additive white Gaussian noise (AWGN) channel with and without variable transmission power at the nodes.We have imposed a guard zone around each receiver node in the network to modify the shot noise model to this channel access scheme and demonstrate the improvement in pernode throughput the guard zone.

Abstract:

For exactly analyzing the course of the coupling impact of auto and protective guard pillar, it’s especially important to get the analytical solution of the coefficient of horizontal subgrade reaction of the horizontal column of protective guard pillar. Using the reaction relationship of soil density and horizontal load ,we build up the estimate theory of the coefficient of horizontal subgrade reaction, with a simple form, describing the relationship of horizontal subgrade reaction and horizontal displacement. Using the Mohr-coulomb yield criterion and the finite element numerical simulation result of ABAQUS, we found that during the column rotary deformation, the coefficient of horizontal subgrade reaction is not a constant ,but it will be smaller and smaller with the development of the deformation. Plastic yield of protective guard pillar and earth coupling model soil caused by horizontal load depends on the difference in value of the max stress component and the min stress component, at the same time raising a theoretical formula of the coefficient of horizontal subgrade reaction and ultimate bearing capacity of soil and setting the theoretical model of coefficient of horizontal subgrade reaction under the horizontal load ,to provide a reference of design and analyze for the practical project.

Abstract:

A test for neglected nonlinearities in regression models is proposed. The test is of the Davidson-MacKinnon type against an increasingly rich set of non-nested alternatives, and is based on sieve estimation of the alternative model. For the case of a linear parametric model, the test statistic is shown to be asymptotically standard normal under the null, while rejecting with probability going to one if the linear model is misspecified. A small simulation study suggests that the test has adequate finite sample properties, but one must guard against over fitting the nonparametric alternative.

Abstract:

Purpose Mathematical models are constructed at the interface between practice, experience and theories. The function of models puts us on guard against the privilege granted to what is accepted as abstract and formal, and at the same time puts us on guard against a static and phenomenological conception of knowledge. The epistemology of models does not suppress in any way the objectives of science: only, a dogmatic conception concerning truth is removed, and dynamic and dialectical aspects of monitoring are stressed to establish the most viable model. The purpose of this paper is to examine hybrid methodologies (inductive-deductive) that may either propose hypothetical causal relations and seek support for them in field data or detect causal relations in field data and propose hypotheses for the relations detected. Design/methodology/approach The authors follow a dialectical analysis for a type of inductive-deductive model. Findings In this work, the authors present an inductive-deductive methodology whose practical result satisfies the Hegelian dialectic. The consequent implication of their mutual reciprocal integration produces abstractions from the concrete that enable thought. The real problem in this case is a given ontological system or reality. Originality/value The essential elements of the models – variables, equations, simulation and feedback – are studied using a dialectic Hegelian theory.

Abstract:

The airtightness of eight apartment buildings containing six to 11 units each on three or four floors was tested with and without guard-zone pressure, that is, with and without consideration of internal leakages. The layouts of these buildings varied: two of them had no central stairwell; in two other buildings, only some of the apartments were connected to the central stairwell; and the third type had all apartments connected to a central stairwell. Airtightness tests were performed with and without guard-zone pressure conditions. During these tests, two to eight BlowerDoor systems were used simultaneously to create guard-zone pressure conditions. In this report, the authors evaluate the test results of three buildings of different layout types. Furthermore, a reference model for the natural air permeability of all construction materials used in the interior and exterior envelopes of each apartment was created for two buildings in accordance with the German Industrial Standards (DIN). We present the results of this assessment and put them in context with the airtightness tests with and without guard-zone pressure. The results indicate that the air leakage contribution of internal partitions is significant, namely 32% and 27%. As this affects sound transmission, fire protection, odor transfer, and the quality of ventilation, it is essential to assess the airtightness of not only the exterior but also the interior envelope of each apartment.

Abstract:

Seasonal and diurnal stomatal conductance, leaf transpiration, and soil water contents of two shrubs of Hippophae rhamnoides L. subsp. Sinensis Rousi and Caragana korshinskii Kom., two trees of Malus pomila Mill. and Robinia pseudoacacia L., and a forb, Artemisia gmelinii, were measured in field of the semiarid Loess Plateau, north China, during the growing season of 2002. We developed a dynamic, nonlinear semi-mechanistic model to relate stomatal conductance of these plants to soil water potential, incident photon flux density, vapour pressure deficit, and partial CO2 pressure, on leaf surface. The model can be easily adapted to ecosystem simulation because of its mathematical simplicity. Guard-cell osmotic pressure at zero light intensity, apparent elastic modulus of guard cells per leaf area, half-saturation light intensity, maximum light-inducible osmotic pressure, soil-to-leaf resistance at zero plant water potential, sensitivity of soil-to-leaf resistance to xylem water potential, and plant body water capacitance, are independent parameters of the model. The model was fitted to the field data of the five species with a non-linear least-square algorithm to obtain the parameters. The result indicates that the model explained, on average, 88% of seasonal and diurnal variation of stomatal conductance for the five species, in comparison with 67% of variation explained by an early model without plant body water capacitance. Comparisons of the physiological parameters among the species show that the woody species exhibited more tolerance for water stresses than the forb because of their higher dark osmotic pressure, greater capability of seasonal and diurnal osmotic regulation, and stiffer guard cell structure (or smaller stomatal density or both). A decreasing trend of soil-to-leaf resistance from the trees to the shrubs to the forb was found in this study. Midday depression of transpiration and stomatal conductance may or may not occur, depending on the magnitude of body water capacitance.
