A Technical Tool for the Agricultural Machinery Performance Assessment

The features of continuous timing of operations during control shifts are described. An electronic universal chronometer has been proposed, which makes it possible to perform the timing of process steps for the performance assessment of agricultural units and to determine, using GPS, such indicators as the path traveled when performing the main process step and productivity.

Decentralization Reforms in Developing Countries Designed to Champion the Interests of Central Politicians and not Grassroots Development

Decentralization has been considered as a powerful tool for enhancing development. However, after nearly four decades of implementing decentralization in many countries in the Global South, the evidence suggests that the impact of decentralization on development is weak and uninspiring. This article argues that the design of a decentralization program is always critical with regard the extent to which it can promote development. The evidence across the developing countries demonstrates that the motivations behind decentralization are typically not politically neutral, political interests have been the key motivation behind the adoption of various types of decentralization programs in the developing countries. As a result, the faith in decentralization as a technical tool that could propel grassroots development needs to be reconsidered, since political interests and not development are the main determinants of decentralization. This is because, in practice, the decentralization designs in many developing countries tend to limit rather than expand the political, fiscal, and administrative powers of subnational governments, while the center retains control. This severely limits the development potential of subnational governments.

Traffic Parking Management Analysis Using GIS Method

With the increased number of vehicles, parking supplies should meet parking demands. In urban areas due to Irregular construction and excessive population growth cities required re-planning and site selection of parking places. In this have a look at, technical evaluation became developed to determine vicinity-based totally parking call for with the aid of the use of Geographic data gadget (GIS). After doing observe on parking call for and deliver balance, the region-allocation strategies have been implemented to decide the great places of parking, depending on parking call for. This technical tool becomes tested for an urban location. As a result, a creative records processing method became evolved to determine the quality locations of vehicle parking. Geographic statistics structures (GIS) technology has been used for a numerous plans inside the transportation industry. This GIS device has come with many new makes use of, benefits, and demanding situations. This challenge can display the ability of GIS to help transportation evaluation and planning.

Reiterman’s Theorem on Finite Algebras for a Monad

Profinite equations are an indispensable tool for the algebraic classification of formal languages. Reiterman’s theorem states that they precisely specify pseudovarieties, i.e., classes of finite algebras closed under finite products, subalgebras and quotients. In this article, Reiterman’s theorem is generalized to finite Eilenberg-Moore algebras for a monad T on a category D: we prove that a class of finite T -algebras is a pseudovariety iff it is presentable by profinite equations. As a key technical tool, we introduce the concept of a profinite monad T ^ associated to the monad T , which gives a categorical view of the construction of the space of profinite terms.

Advances in single-cell sequencing: insights from organ transplantation

Single-cell RNA sequencing (scRNA-seq) is a comprehensive technical tool to analyze intracellular and intercellular interaction data by whole transcriptional profile analysis. Here, we describe the application in biomedical research, focusing on the immune system during organ transplantation and rejection. Unlike conventional transcriptome analysis, this method provides a full map of multiple cell populations in one specific tissue and presents a dynamic and transient unbiased method to explore the progression of allograft dysfunction, starting from the stress response to final graft failure. This promising sequencing technology remarkably improves individualized organ rejection treatment by identifying decisive cellular subgroups and cell-specific interactions.

Large N behaviour of the two-dimensional Yang–Mills partition function

We compute the large N limit of the partition function of the Euclidean Yang–Mills measure on orientable compact surfaces with genus $g\geqslant 1$ and non-orientable compact surfaces with genus $g\geqslant 2$ , with structure group the unitary group ${\mathrm U}(N)$ or special unitary group ${\mathrm{SU}}(N)$ . Our proofs are based on asymptotic representation theory: more specifically, we control the dimension and Casimir number of irreducible representations of ${\mathrm U}(N)$ and ${\mathrm{SU}}(N)$ when N tends to infinity. Our main technical tool, involving ‘almost flat’ Young diagram, makes rigorous the arguments used by Gross and Taylor (1993, Nuclear Phys. B400(1–3) 181–208) in the setting of QCD, and in some cases, we recover formulae given by Douglas (1995, Quantum Field Theory and String Theory (Cargèse, 1993), Vol. 328 of NATO Advanced Science Institutes Series B: Physics, Plenum, New York, pp. 119–135) and Rusakov (1993, Phys. Lett. B303(1) 95–98).

Nilpotent endomorphisms of expansive group actions

We consider expansive group actions on a compact metric space containing a special fixed point denoted by [Formula: see text], and endomorphisms of such systems whose forward trajectories are attracted toward [Formula: see text]. Such endomorphisms are called asymptotically nilpotent, and we study the conditions in which they are nilpotent, that is, map the entire space to [Formula: see text] in a finite number of iterations. We show that for a large class of discrete groups, this property of nil-rigidity holds for all expansive actions that satisfy a natural specification-like property and have dense homoclinic points. Our main result in particular shows that the class includes all residually finite solvable groups and all groups of polynomial growth. For expansive actions of the group [Formula: see text], we show that a very weak gluing property suffices for nil-rigidity. For [Formula: see text]-subshifts of finite type, we show that the block-gluing property suffices. The study of nil-rigidity is motivated by two aspects of the theory of cellular automata and symbolic dynamics: It can be seen as a finiteness property for groups, which is representative of the theory of cellular automata on groups. Nilpotency also plays a prominent role in the theory of cellular automata as dynamical systems. As a technical tool of possible independent interest, the proof involves the construction of tiered dynamical systems where several groups act on nested subsets of the original space.

Performance is Political

Performance management is usually presented as a technical tool to monitor policies and programmes. Performance indicators are presented as neutral and as having been developed in pursuit of economy, efficiency and effectiveness. According to this approach, if properly conceptualised and constructed, performance indicators illuminate the extent to which agencies or services are achieving goals and provide accountability. In contrast, understanding performance indicators as political requires examination of their social as well as their technical aspects. From this perspective, the effectiveness of an indicator as a means to measure performance is not as important as other roles, such as embedding policy and shaping practice. Accordingly, performance management represents a significant technology of control over social work. It acts as a powerful determinant of which forms of practice are approved by deciding which of them are drawn into the accountability framework and are therefore authorised.

Introduction to the anthropology of photography in Serbia

Despite significant strides from the beginning of the 20th century, there was no systematic or institutionalized reflection on photography in Serbian ethnology and anthropology until the 1980s. Until then, photography was mainly used as an additional technical tool for field recording, documenting, and presenting field materials in museums or scientific institutions. However, since the end of the 20th, and especially at the beginning of the 21st century, an increasing number of social scientists have included photography in their works, either through historical and theoretical reflection or through practical use in specific research. This step can be related to the institutionalization of the sub discipline of visual anthropology in Serbia. The paper presents the assumption that both flows are part of a broader process called the visual turn, and the associated flourishing of systematic thinking about visual culture. In this paper, we aim to reconstruct the main features of the visual turn in the local academic community and point out some of its consequences. In addition, our goal is to present the most important achievements related to the mentioned turn, and consider their impact on recent examples of thinking about photography, i.e. its use in ethnological and anthropological research in Serbia. This paper emphasizes the examples that are important in the theoretical, methodological, or applied-scientific framework.
