Increasingly rapid economic development resulted in many new companies springing up and creating a tight business competition. To be able to maintain business continuity, companies must be able to make a careful planning and control of the costs. Planning and control can be realized with the budget as a mean of control. Controlling costs by the company are intended to enable companies to minimize costs. At minimal costs the company will be able to achieve the profit target by more optimal as primary destinations in general. In connection to this, the purpose of this study was to determine the costs of the company budget preparation, budget realization costs and revenues, as well as the role of the budget as a mean of control in achieving its profit target. The research was conducted at PT ABC located in Bogor. PT ABC is one of the private companies engaged in construction services focusing on building the types of housing. This kind of development focus includes the construction of a building without infrastructure development. The study of PT ABC shows that the preparation of the company's budget is based on field survey and accompanying informations on the revenue budget and previous projects. In the implementation of the work there was an increase in the actual cost, thus resulting difference in the budget and actual costs. The occurrence of this difference will reduce the company’s profits. Overall budgets have created optimal control of the realization of the costs incurred. Budget serves as guidelines and benchmarks maximum value in any cost incurred by the company. However, in the implementation of the work there are still some shortcomings, resulting cost difference persists. This difference occurs because lack of oversight of the usage of raw materials. Companies must be able to improve control over the using of raw materials to be better coordinated. Increased control is evidenced by the increase in its profit target achievement on the next project. In the subsequent project, company managed to improve the performance of surveillance so that the difference in costs declined and its optimal profit target can be achieved.

The development of knowledge and the technology is rapidly changing causing tight competition in the business. To survive this competition and maintain sustainability, companies conduct various kinds of ways, one of which is by way of monitoring the system that existed in the corporate setting. One of the systems must be considered is a system of corporate sales and also the process of billing receivable. This is because sales are the activities that will produce revenues or profits for the company to maintain sustainability of its business. In this receivable billing activities, one must also considere whether or not the profit or assets owned by the company will give returns. The purpose of this research is to find out accounting information system sales, to know the process of billing receivable, and to know accounting system information of sales on the process billing receivable. The research was conducted in PT. Semut Merah Tangguh – branch Ciawi, Bogor. PT. Semut Merah Tangguh is the distributor company of consumer goods from PT.Unilever. The main activities of PT.

The Influence of Profitability, Solvency, Auditor’s Opinion and Reputation to Audit Delay (The Empirial Study of Manufacturing Companies Listed on Indonesia Stock Exchange 2012-2013)
Authors: . Triandi , Hadiyanti Rizki
Published: February 2020

The presentation of financial statements of a go public company towards its concerned parties requires a punctual publishing of financial statements. Punctuality reflects the qualitative characteristics of financial statements reporting according to the accounting principal that is generally used in Indonesia. Such qualitative characteristic is relevant, meaning that the information contained in the financial statements must be able to influence the decision makers, so the reports must be delivered punctually. Relevant has the close connection to timeliness of reporting. Timeliness also related to the time difference between date of financial statements and date of auditor’s report, which indicates the length of time of auditing settlements, or called as audit delay as the dependent variable. This study aims to measure empirically the factors affecting audit delay of the listed manufacturing companies on Indonesia Stock Exchange. They are profitability, solvency, auditor’s opinion and reputation as the independent variables. The samples of this research consist of 147 manufacturing companies in Indonesia Stock Exchange during 2012-2013 and selected by purposive sampling. The data used is secondary data; which are audited financial statements of 147 samples. The data analysis used methods to prove the hypothesis are descriptive statistics, classic assumptions test, multiple regression models, and the determinant coefficient.

The study finds that three out of four independent variables influence insignificantly to audit delay; they are profitability, solvency and auditor’s opinion. Only auditor reputation influences audit delay significantly. The simultaneous testing concluded that all independent variables influence the dependent variable significantly.
Analisis Penerapan PSAK 5 (Revisi 2009) terhadap Pengungkapan Segmen Operasi pada Perusahaan Manufaktur yang Terdaftar di Bursa Efek Indonesia (BEI)
Authors: Pardede Robert Pius , Ernawati Tri
Published: February 2020

The International Accounting Standards Board (IASB) is committed to improve their standards’ quality, which is the global accounting standards that reflect information in financial statements as transparent and comparable for public purposes. The International Accounting Standards (IAS) and the International Financial Reporting Standards (IFRS) provide guidelines in creating and interpreting companies’ financial statements (Iatridis & Dalla, 2011). The purpose of this research was to assess the impact of the application of PSAK 5 (revised 2009). PSAK 5 (revised 2009) requires segment disclosure based on the internal reporting reviewed by the operation decision maker. PSAK 5 (revised 2000) requires companies to disclose segments information based on the format of the primary and secondary segments as identified per products / services that generate the same level of risk and return. The six analytical frameworks developed for this research, namely: (1) analysis of the presentation of segment information based on PSAK 5 (revised 2000) versus PSAK 5 (revised 2009), (2) analysis of the determination and identification of operational decision-making, (3) the analysis of the definition and identification operating segments between industry sectors, (4) analysis of segment aggregation, (5) analysis of determination of the reportable segments, and (6) analysis of reported segment disclosures. In conclusion, generally, the disclosure of segment information based on PSAK 5 (revised 2009) by using the management approach yields a more complete segment report, by conveying more relevant segmental information from the standpoint of management's internal performance than the previous standard, which was PSAK 5 (revised 2000).

This research found significant changes related to an increase in the disclosure of segment disclosure in business segments, segment aggregation, and basic information on company's segmental performance measurement in Indonesia.

Published: February 2020

As a member of G-20 Forum, Indonesia starts to adopts the International Financial Reporting Standard (IFRS) as a requirement to fulfill the demands and needs of financial statements users. The adoption of international accounting standards into national accounting standards aim to create financial statements that have high level of credibility and accountability. IFRS requests the requirement of high level of disclosure items so the value of companies will increase, management will have high level of accountability to run the company, that allows changes on the financial statements, for example that can change the length of financial statements. The purpose of this study is to know the effect of IFRS adoption on the length of financial statements, and to know the content of financial statements before and after IFRS adoption. This study was conducted by dividing financial statements into two sections, which are major statements and notes to the financial statements.  The financial statements used in this study are 2008 and 2013. The sample was selected by purposive sampling method and analyzed using parametric and non-parametric tests. Results of this study show that major statements and notes to the financial statements experienced an increase in length after adopting IFRS. Notes to financial statements experiencing the most significant increase in length after adopting IFRS. On the major statements, the increase is caused by other comprehensive income account. While on the notes to the financial statements, increase is caused by implementation of  PSAK 1 which requires the high level of disclosures. The increase mainly occured in accounting policy on the financial statements.

Economic in Indonesia is growing rapidly. One of the supporting factors economic development in Indonesia is the construction field which is growing from year to year. The construction completion process carried out by a construction company has a different period of time depending on the request of the employer. The construction companies measure their gross profit by using the percentage settlement method or the recovered cost method depends on the contract. In general, the contractor company is still wrong in using these methods so that the company does not know clearly the gross profit obtained.The purpose of this study was to determine the recognition of gross profit by applying the recoverable cost method and the percentage of completion method of PT Mitra Menara Mandiri and knowing the factors that influence the selection of methods in the recognition of gross profit using the percentage settlement method and the recoverable cost method at PT Mitra Menara Mandiri.The results of the analysis of the implementation of the cost recovery method and the percentage settlement method of the company's gross profit at PT Mitra Menara Mandiri are still not in accordance with generally accepted accounting principles in terms of determining the recognition of the revenue applied. There is a weakness in the company in recording journals, such as the company does not record business journals when receiving a job and the company does not record if the company conducts billing terms. Therefore, the company should at the time of conducting the billing the company records the journal and records the accounts receivable journal at the time of receiving the job to avoid losing data at the time PT Mitra Menara Mandiri receives cash on the receivables that have been billed.

Published: February 2020

BACKGROUND: Jackfruit Seeds (Artocarpus heterophyllus L.) are plants that are thought to be able to reduce blood sugar levels.
AIM: The purpose of this study was to prove the activity of jackfruit seeds in reducing blood glucose levels in gestational diabetic rats induced by streptozotocin and in silico study virtual screening through molecular docking to find out the compounds in jackfruit seeds that have interaction with sulfonylurea receptors.
METHODS: The animals used in this study were Sprague Dawley strain pregnant female rats which were divided into six groups, namely the normal control group, negative control, positive control, various dose groups (100 mg/kg BW, 200 mg/kg BW, 400 mg/kg BW). After the rat was pregnant, the rats were induced first with streptozotocin so that the rats had hyperglycemia. Blood glucose levels were measured on the 14th day after treatment. The data obtained were statistically tested by one-way ANOVA test followed by the HSD Tukey test. Virtual screening was done using PLANTS 1.2 software.
RESULTS: The results showed that all groups of ethanol extract 70% of jackfruit seeds could reduce blood glucose levels. The biggest decrease in blood glucose levels occurred at dose 3 with a dose of 400 mg/kg BW which was 61.73%, comparable to positive control glibenclamide. The results of virtual screening with molecular docking showed that betacarotene epoxide compounds have better affinity than glibenclamide as a comparative compound.
CONCLUSION: It can be concluded that jackfruit seeds beta-carotene epoxide has the potential to reduce blood sugar levels by inducing insulin secretion.

Published: February 2020

We evaluated growth of Bluegill Lepomis macrochirus in 24 small Kansas impoundments to understand variability in populations statewide. We assigned ages to 1,323 Bluegill, and when combined, growth parameters using the Ogle–Isermann parameterization of the von Bertalanffy growth model were: L∞ = 228 mm, K = 0.25, and t152 = 3.10 y. Growth was variable among the 24 populations and t152 (time to reach 152 mm total length) ranged from 1.56 to 4.87 y. We selected four representative limnological variables (latitude, maximum depth, total nitrogen, and total phosphorus) and four representative catch variables (catch-per-effort [CPE] of Bluegill, proportional size distribution of 178-mm Bluegill, CPE of stock-length Largemouth Bass Micropterus salmoides, and CPE of Gizzard Shad Dorosoma cepedianum) to elucidate mechanisms that explained t152 in Bluegill populations. We fit all subset candidate models using the eight variables to predict t152. Top candidate models (corrected Akaike's information criterion scores within two units of the most parsimonious model) comprised a confidence model set, and we used model-weighted averaging to calculate parameter estimates with 95% confidence intervals for each independent variable present in the confidence model set to develop a single explanatory model. The final model suggested that Bluegill size structure, latitude, and CPE of stock-length Largemouth Bass affected Bluegill growth, whereas a smaller effect was attributed to CPE of Gizzard Shad. Combined, these variables explained 40% of variation in observed Bluegill growth rate. Results from this study summarize Bluegill growth in Kansas and highlight variation in growth rates across small impoundments. Further, they suggest that Bluegill size structure, latitude, and relative abundance of stock-length Largemouth Bass are important factors regulating Bluegill growth in small Kansas impoundments.

Video Watermarking for Copyright Protection with Genetic-Based Frame
Selection
Authors: Saud S. Alotaibi Saud S. Alotaibi
Published: February 2020

Recently, video watermarking has received much consideration. Several applications in
a variety of domains have been implemented, and many are progressing. This paper intends to
formulate a novel video watermarking framework that includes three stages: (i) Optimal video
frame prediction, (ii) A watermark embedding process, and (iii) A watermark extraction process.
In the proposed model, the optimal frame prediction is carried out using the deep belief network
(DBN) framework. Initially, randomly chosen frames from each video are used as the input to a
genetic algorithm (GA) model that optimally chooses the frames such that the peak signal-tonoise ratio (PSNR) should be maximal. The frames are assigned with a label of one or zero, where
a label of one denotes a frame with better PSNR (can select for embedding process) and a label of
zero denotes the frame with reduced PSNR (cannot be used for embedding). Consequently, a data
library is formed from the obtained results, where each video frame is determined with their graylevel cooccurrence matrix (GLCM) features and labels (can embed or not), which is then trained
in the DBN framework, from which the optimal frames can be predicted efficiently while testing.
Furthermore, the watermark embedding process and watermark extraction process are carried out,
and thus, the image can be embedded within the optimally selected frames.

The technology revolution in wireless communications and micro-electro-mechanical
systems (MEMS) directly affects the development of wireless sensor networks (WSNs), which
are used in several application areas, including the military, home, and environment. One of the
best categories of routing networks in WSNs are hierarchical protocols (cluster-based). The wellknown protocols in this category include the Low Energy Adaptive Clustering Hierarchy
(LEACH). However, the LEACH is vulnerable to many attacks. To provide cryptographic
protection against outsider attacks, a modified version of LEACH, called Enhancing Secure
LEACH (MS-LEACH) protocol, is used. MS-LEACH enhances security but increases power
consumption. To maintain an acceptable level of security and decrease the power consumption of
secure LEACH protocols, the present research proposes a Secure Lightweight LEACH (SLWLEACH) scheme. The simulation results show that this proposed SLW-LEACH protocol
outperforms the MS-LEACH in terms of ne

Abstract. During the OMO (Oxidation Mechanism Observation) mission, trace gas measurements were performed onboard the HALO (High Altitude LOng range) research aircraft in summer 2015 in order to investigate the outflow of the south Asian summer monsoon and its influence on the composition of the Asian Monsoon Anticyclone (AMA) in the upper troposphere over the eastern Mediterranean and the Arabian Peninsula. This study focuses on in situ observations of hydrogen peroxide (H2O2) and organic hydroperoxides (ROOH), as well as their precursors and loss processes. Observations are compared to steady state calculations of H2O2, methyl hydroperoxide (MHP) and inferred unidentified hydroperoxide (UHP) mixing ratios. Measurements are also contrasted to simulations with the general circulation ECHAM/MESSy for Atmospheric Chemistry (EMAC) model. We observed enhanced mixing ratios of H2O2, MHP and UHP in the AMA relative to the northern hemispheric background. Highest concentrations for H2O2 and MHP were found in the southern hemisphere outside the AMA, while for UHP, highest concentrations were found within the AMA. In general, the observed concentrations are higher than steady-state calculations and EMAC simulations. Especially in the AMA, EMAC underestimates the H2O2 and ROOH mixing ratios. Longitudinal gradients indicate a pool of hydroperoxides towards the center of the AMA, most likely associated with upwind convection over India. This indicates main contributions of atmospheric transport to the local budgets of hydroperoxides along the flight track, explaining strong deviations to steady-state calculations which only accounts for local photochemistry. Deviations to EMAC simulations are most likely due to uncertainties in the scavenging efficiencies for individual hydroperoxides in deep convective transport to the upper troposphere, corroborated by a sensitivity study. It seems that the observed excess UHP is excess MHP transported to the west from an upper tropospheric source related to convection in the summer monsoon over South-East Asia.
Early morning peaks in the diurnal cycle of precipitation over the northern coast of West Java and possible influencing factors
Authors: Yulihastin Erma , Wahyu Hadi Tri , Sari Ningsih Nining , Ridho Syahputra Muhammad
Published: February 2020

Abstract. The diurnal cycles of precipitation over the northern
coast of West Java have been studied using the Tropical Rainfall Measuring
Mission (TRMM) Real Time Multi-satellite Precipitation Analyses (TMPA-RT)
products with records spanning from 2000 to 2016, with emphasis on the
occurrences of early morning precipitation peaks. Diurnal precipitation over
the study area during November to March is basically characterized by
precipitation peaks that occur in the afternoon to evening time
(15:00–21:00 LT), but secondary peaks in the night to morning time (01:00–07:00 LT) are also pronounced in January and February. The harmonic analysis method
was then applied to data of January and February to objectively determine
the diurnal phase and classify the timing of precipitation for each day into
three categories, i.e. afternoon-to-evening precipitation (AEP), early
morning precipitation (EMP), and late morning precipitation (LMP) with peaks
that occur in the time windows of 13:00–24:00, 01:00–04:00, and
05:00–12:00 LT, respectively. In terms of frequency of occurrence, AEP,
EMP, and LMP constitute 55 %, 18.9 %, and 26.1 % of total samples
of precipitation events. In spite of the smallest percentage, EMP events are
characterized by seaward (as well as landward) propagation, flat phase
distribution, and large mean amplitudes. The propagating characteristics of
EMP are more prominent, with indications of stronger connectivity between
precipitation systems over land and ocean, when data are composited by
taking the 99th percentile values in each grid to represent extreme
precipitation events. The flat phase distribution of EMP events suggests
that the timing of coastal precipitation is not necessarily locked to the
phase of land–sea breezes, thus allowing precipitation to occur more
randomly. Furthermore, the role of the South China Sea cold tongue (SCS-CT) and
cross-equatorial northerly surge (CENS) as influencing factors for the
occurrences of the EMP event have also been investigated. In agreement with
previous studies, we confirmed that the SCS-CT generally prevails in January
and February, and morning precipitation events over the northern coast of
West Java mainly occurred when there was more enhanced sea surface
temperature (SST) cooling in the South China Sea. Additionally, we found
that CENS is the most differential factor with regard to the phase of
coastal precipitation. In this case, CENS is positively correlated with
SCS-CT and, when associated with EMP events, concurrent enhancement of CENS
and SCS-CT is connected to a narrow channelling of strong surface northerly
wind anomalies just offshore of Indochina and the Malay Peninsula.
Reviews and syntheses: The mechanisms underlying carbon storage in soil
Authors: Basile-Doelsch Isabelle , Balesdent Jérôme , Pellerin Sylvain
Published: February 2020

Abstract. Scientific research in the 21st century has considerably improved our knowledge of soil organic matter and its dynamics, particularly under the pressure of the global disruption of the carbon cycle. This paper reviews the processes that control C dynamics in soil, the representation of these processes over time, and their dependence on variations in major biotic and abiotic factors. The most recent advances in soil organic matter knowledge are: – Most organic matter is composed of small molecules, derived from living organisms, without transformation via additional abiotic organic polymerization. – Microbial compounds are predominant in the long term. – Primary belowground production contributes more to organic matter than aboveground inputs. – Contribution of less biodegradable compounds to soil organic matter is low in the long term. – Two major factors determine the soil organic carbon production yield from the initial substrates: the yield of carbon used by microorganisms and the association with minerals, particularly poorly crystallized minerals, which stabilize microbial compounds. – Interactions between plants and microorganisms and between microbial communities affect or even regulate carbon residence times, and therefore carbon stocks. Farming practices therefore affect soil C stocks not only through carbon inputs but also via their effect on microbial and organomineral interactions.
New IMA CNMNC guidelines on combustion products from burning coal dumps

Abstract. New IMA CNMNC guidelines were established for minerals
crystallizing on burning coal dumps. These phases are now acceptable as
minerals, if it can be proven that the fire responsible for the formation of
these phases is the result of natural events. In that case, these substances
have to be treated as normal new mineral species, and their complete
characterization has to be submitted to the CNMNC via the new mineral proposal
form. The authors are specifically asked, however, to give strong arguments
in the proposal clearly demonstrating the non-anthropogenic origin of the
burning process.
Which rainfall metric is more informative about the flood simulation performance? A comprehensive assessment on 1318 basins over Europe
Authors: Camici Stefania , Massari Christian , Ciabatta Luca , Marchesini Ivan , Brocca Luca
Published: February 2020

Abstract. The global availability of satellite rainfall products (SRPs) at an increasingly high temporal/spatial resolution has made possible their exploitation in hydrological applications, especially over in-situ data scarce regions. In this context, understand how uncertainties transfer from SRPs into flood simulation, through the hydrological model, is a main research question. SRPs accuracy is normally characterized by comparing them with ground observations via the calculation of categorical (e.g., threat score, false alarm ratio, probability of detection) and/or continuous (e.g., bias, root mean square error, Nash-Sutcliffe index, Kling-Gupta efficiency index, correlation coefficient) metrics. However, whether these metrics are informative about the associated performance in flood simulations (when the SRP is used as input to an hydrological model) is an underdiscussed research topic. This study aims to relate the accuracy of different SRPs both in terms of rainfall and in terms of flood simulation. That is, the following research question are addressed: is (are) there appropriate performance metric (s) to drive the choice of the best performing rainfall product for flood simulation? To answer this question three SRPs, namely the Tropical Rainfall Measurement Mission Multi-satellite Precipitation Analysis, TMPA; the Climate Prediction Center Morphing algorithm, CMORPH, and the SM2RAIN algorithm applied to the ASCAT (Advanced SCATterometer) soil moisture product, SM2RAIN-ASCAT, have been used as input into a lumped hydrologic model (MISDc, “Modello Idrologico Semi-Distribuito in continuo”) on 1318 basins over Europe with different physiographic characteristics. Results have suggested that, among the continuous metrics, correlation coefficient and Kling-Gupta efficiency index are not reliable scores to select rainfall product performing best for hydrological modelling whereas bias and root mean square error seem more appropriate. In particular, by constraining the relative bias to values lower than 0.2 and the relative root mean square error to values lower than 2, good hydrological performances (Kling-Gupta efficiency index on discharge greater than 0.5) are ensured for almost 75 % of the basins fulfilling these criteria. Conversely, the categorical scores have not provided suitable information to address the SRPs selection for hydrological modelling.

Abstract. We revisit and shed light on the millennium-old hydrogeology textbook The Extraction of Hidden Waters by the Persian mathematician and engineer
Karaji. Despite the nature of the understanding and conceptualization of the
world by the people of that time, ground-breaking ideas and descriptions of
hydrological and hydrogeological perceptions such as components of
hydrological cycle, groundwater quality and even driving factors for
groundwater flow were presented in the book. Although some of these ideas
may have been presented elsewhere, to the best of our knowledge, this is the
first time that a whole book was focused on different aspects of hydrology
and hydrogeology. More importantly, we are impressed that the book is composed in a way that covered all aspects that are related to an engineering project, including technical and construction issues, guidelines
for maintenance, and final delivery of the project when the development and
construction were over. We speculate that Karaji's book is the first of its
kind to provide a construction and maintenance manual for an engineering
project.

PURPOSE: The purpose of this study was to compare expression patterns of inflammatory cytokines between subacromial bursitis and glenohumeral (GH) joint synovitis in full thickness rotator cuff (RC) tear patients with severe pain.MATERIALS AND METHODS: We were able to obtain enough tissue from nine subacromial bursitis and GH synovitis patients at the same time during surgery and evaluate them. We compared mRNA expression of inflammatory cytokines between the two groups using Reverse Transcription-Polymerase Chain Reaction (RT-PCR).RESULTS: Relative mean mRNA expression of IL-1beta, IL-6, TNF-alpha, COX-1, COX-2 and SDF-1 in the tissues of subacromial bursitis and GH synovitis patients did not show significant differences.CONCLUSION: GH synovitis may be another source of shoulder pain with subacromial bursitis in full thickness RC tear patients with severe pain.

Published: February 2020

Scientific workflows rely on provenance to be understandable, reproducible and trustworthy. Nowadays, there is a growing demand for interoperability between provenance data generated from heterogeneous workflow management systems. To address this issue, some provenance models have been proposed by extending PROV to support specific requirements of scientific workflows. In this paper, we present two prominent provenance models for scientific workflows, PROV-Wf and ProvOne, which are specializations of PROV, and compare their elements and relationships. Our goal is to provide an overview of each one and to support the choice for the most suitable for a specific context.

An efficient algorithm for the Closest String Problem
Authors: Vilca Omar , De Freitas Rosiane
Published: February 2020

The closest string problem that arises in computational molecular biology and coding theory is to find a string that minimizes the maximum Hamming distance from a given set of strings, the CSP is NP-hard problem. This article proposes an efficient algorithm for this problem with three strings. The key idea is to apply normalization for the CSP instance. This enables us to decompose the problem in five different cases corresponding to each position of the strings. Furthermore, an optimal solution can be easily obtained in linear time. A formal proof of the algorithm will be presented, also numerical experiments will show the effectiveness of the proposed algorithm.

Redes aquáticas possuem diversas aplicações potenciais, como preservação do ecossistema e prevenção de desastres ambientais. Como sinais de radio-frequência são rapidamente absorvidos debaixo d’água, estas redes utilizam o sinal acústico como sistema de comunicação. Comparada com redes terrestres, redes acústicas possuem características únicas, como baixa largura de banda, alta latência e grande atraso de propagação. Com tantas restrições, deve-se ressaltar a influência exercida por modems acústicos, cujas características podem afetar o desempenho da rede. Uma vez que modems de baixo custo são mais acessíveis, se faz necessária uma boa compreensão acerca de seu funcionamento. Este artigo tem por objetivo analisar a performance da comunicação acústica a partir da comparação entre as taxas de transmissão teóricas e reais obtidas por um modem de baixo custo. Experimentos reais foram realizados, onde foi possível identificar o comprometimento nas taxas de transmissão, deteriorada pelos efeitos dos atrasos de propagação no meio.

Com a crescente adoção de sistemas distribuídos de larga escala, tais como clusters para cloud computing, as atividades de implantação e configuração destas soluções se tornam consideravelmente mais complexas. Uma solução promissora é dotar tais sistemas com capacidades de autogerenciamento e diversos padrões de projeto para Sistemas Self-Adaptive estão disponíveis na literatura. Alguns são mais efetivos para operação em ambientes que sugerem a adoção de arquiteturas mais centralizadas. Outros apresentam melhores resultados ao operar de forma mais distribuída. Em ambientes altamente dinâmicos e incertos, no entanto, é difícil encontrar uma única solução efetiva para todos os cenários experimentados. Este trabalho apresenta um modelo adaptativo para implementação de Sistemas Self-Adaptive de larga escala que realizam autogerenciamento com diferentes graus de centralização. Os resultados obtidos mostram que o modelo apresenta desempenho satisfatório tanto em situações onde o sistema monitorado e o ambiente sugerem a adoção de topologias mais centralizadas, quanto em situações onde padrões mais descentralizados apresentam melhor custo-benefício.
