The Efficiency of Requesting Process for Formal Business-Documents in Indonesia: an Implementation of Web Application Base on Secure and Encrypted Sharing Process

In recent business practices, the need of the formal document for business, such as the business license documents, business domicile letters, halal certificates, and other formal documents, is desperately needed and becomes its own problems for businesses, especially for small and medium enterprises. One stop service unit that was conceived and implemented by the government today, has not been fully integrated yet. Not all permits (related with formal document for business) can be completed and finished in one place, businesses are still have to move from one government department to another government department to get a formal document for their business. With these practices, not only a lot of the time and cost will be sacrificed, but also businesses must always fill out a form with the same field. This study aims to assess and identify the problem, especially on applying the formal document for business, and use it as inputs for the development of a web application based on secure and encrypted sharing process. The study starts with a survey of 200 businesses that have applied the formal document for their business, to map the initial conditions of applying the formal document for business in Indonesia . With these applications that are built based on these needs, it is expected that not only the time, cost, and physical effort from both parties are becoming more efficient, but also the negative practices of bureaucratic and economic obstacles in business activities can be minimized, so the competitiveness of business and their contribution for national economy will increase

Efficiency of feedback process in cavity quantum electrodynamics

Utilizing the continuous frequency mode quantization scheme, we study from first principle the efficiency of a feedback scheme that can generate maximally entangled states of two atoms in an optical cavity through their interactions with a single input photon. The spectral function of the photon emitted from the cavity, which will be used as the input of the next round in the feedback process, is obtained analytically. We find that the spectral function of the photon is modified in each round and deviates from the original one. The efficiency of the feedback scheme consequently deteriorates gradually after several rounds of operation.Comment: 11 pages, 5 figures, accepted for publication in Journal of Physics

Maximum efficiency of the collisional Penrose process

We consider collision of two particles that move in the equatorial plane near a general stationary rotating axially symmetric extremal black hole. One of particles is critical (with fine-tuned parameters) and moves in the outward direction. The second particle (usual, not fine-tuned) comes from infinity. We examine the efficiency $\eta$ of the collisional Penrose process. There are two relevant cases here: (i) a particle falling into a black hole after collision is heavy, (ii) it has a finite mass. We show that the maximum of $\eta$ in case (ii) is less or equal to that in case (i). It is argued that for superheavy particles, the bound applies to nonequatorial motion as well. As an example, we analyze collision in the Kerr-Newman background. When the bound is the same for processes (i) and (ii), $\eta =3$ for this metric. For the Kerr black hole, recent results in literature are reproduced.Comment: 18 pages. Typos corrected. Title somewhat modified according to suggestions of editors of PR

Woodworking facilities: Driving efficiency through Automation applied to major process steps

The investment scenario applied to forestry development analyzes the fundamental changes in the production structure, among other things. These changes refer to the priority development of the pulp and paper industry through the chain of large-scale woodworking facilities, where pulp, paper and cardboard manufacturing plants are the key links. Such facilities include sawmilling facilities, wood-processing factories, and timber factories. Those provide a significant economic benefit, so improving them is one of the top priorities. Considering this priority is the purpose of this article. The goal was achieved using common and scientific research methods, including mathematical modeling. Theoretical research resulted in three sets of formulas adapted for evaluating the pulpwood barking from theoretical findings on image recognition. © 2018 Authors

The Efficiency of the Bankruptcy Process. An International Comparison

Failure of projects and firms are an inherent element of growth. Economic growth requires that old activities are phased out to make room for new ones, and that economic resources are reallocated from activities that are no longer profitable. In an economy where most firms are financed by debt to a substantial extent, insolvencies inevitably play an important role in restructuring. Insolvency leads to formal bankruptcy when legal procedures are employed to liquidate the insolvent firm’s assets in order to pay stakeholders fully or partially according to a priority established in law or contracts. In some countries legal procedures exist for restructuring as well as for liquidation. In other countries the restructuring of an insolvent firm is handled informally through negotiation. The economic roles of insolvency procedures are discussed (in Section 2) with an emphasis on dynamic aspects. In discussing the efficiency of insolvency procedures (in Section 3) we distinguish between ex ante and ex post efficiency. Since efficiency ultimately must be evaluated in terms of its dynamic effects, simple efficiency criteria are not easily identified. Formal insolvency procedures in different countries are classified (in Section 4) as more or less creditor or debtor oriented. Legal approaches can also be classified as more or less contractual or statutory. The important interdependence between formal and informal procedures is discussed in Section 5.Thereafter we turn in Section 6 to the empirical evidence on bankruptcy and restructuring in a number of countries with substantial differences in legal approaches to insolvency. We ask in Section 7 what explains the relatively high bankruptcy frequency in Sweden in an international comparison. Is the high frequency an indication of efficiency of procedures or does it indicate that viable firms are forced into bankruptcy unnecessarily?Bankruptcy; Insolvency; Restructuring; Contracting
