The Necessity of Regional Economic Integration: a Lesson for South Asia?
Authors: Khan Md. Rajin Makhdum , Imam Faizah
Published: October 2017

ASEAN and the European Union have showed this world the privileges regional economic integration provides the states. Although Greece and Italy might be the torchbearers of criticism against regional cooperation and integration, these two organizations tend to be some prime examples of necessity of regional economic integration. This dissertation thus focuses on the privileges and advantages that regional economic integration system and organizations deliver to the states aligned within. With the possible and crucial criticisms on mind, the discussion moves forward analyzing if this system is making the countries perform better economically and advance towards domestic development. The dissertation further intends to find out why the South Asian nations might need similar kind of cooperation and why these countries should act more sensible to make the economic integration possible. While remarking the recommendations, the discussion also draws the barriers and the problems that this region might face in order to integrate their economies or enhance their trades. The core argument of this dissertation therefore lies in analyzing the importance of regional economic integration and liberal economics in this modern world and if the South Asian countries need economic integration to develop their domestic economies. The recommendations are to provide the possible ways to run the process and the drawbacks portion mentions the difficulties and barriers to be faced whilst all of these countries’ ongoing strict policies. The argument tries to find out the significance of liberal economics and tribulation of realism in the contemporary world.
Spatial Variability of Soil Aggregate Stability in a Disturbed River Watershed
Authors: Mainuri Zachary Gichuru , Owino James Odhiambo.
Published: October 2017

Analysis of spatial distribution of soil properties like soil aggregate stability presents an important outset for precision agriculture. The study area was classified into different landscape units according to physiographic features namely: mountains, plateaus, uplands, valleys, pen plains, alluvial plains, lacustrine plains and hills and maps were drawn. The objectives of this study were to evaluate the effects of landscape and land use interaction on the spatial variability of aggregate stability. The variability of aggregate stability exhibited spatial dependence (SDP) which helped in the generation of a spatial dependence index (SDI) that was described using semivariogram models. SPD Gaussian(%) ≤ 25% gave a weak spatial dependence, moderate spatial dependence was given by 25% ( SDP ( % ) ≤ 75% and strong spatial dependence by SDP (%) ) 75%, while SDI Gaussian (%) ≤ 25% gave a strong spatial dependence index while moderate spatial dependence index was indicated by 25% ( SDI (%) ≤ 75%, and weak spatial dependence index SDI (% ) ) 75%. Mean Weight Diameters (MWD) of 0.25 – 0.45 represented unstable soils mostly found in wetlands occurring in valleys, mountains, plains, and depressions in hills, 0 55 –0.62 represented moderately stable soils mostly in agricultural and grassland areas which include plateaus, uplands, and plains, while 0.62 – 0.92 represented stable and very stable soils being found in forested areas, mountains and hills. Various interpolation (kriging) techniques capitalized on the spatial correlation between observations to predict attribute values at unsampled locations using information related to one or several attributes that helped in the construction of an aggregate stability prediction map using Empirical Bayesian kriging (EBK) technique.

Theories of Death with a Special Reference to Indian Philosophy
Authors: Sharma Gopinath N.
Published: October 2017

Most of the philosophers deal with the quality of life, assuming a long span covering all phases. Therefore it is a commonly idealized life. But during the course the life as we advance, there are numerous riddles of self and the universe we live in it to encounter. Certain questions that have not only puzzled the common man but also the intellectuals had been like, Is there any meaning behind every happening? How ought we to live? Is there any life after death? Is death as such is the true end of all activities and so on. However, when the subject of death comes the answers through theories or philosophies have not been very convincing or suitable to all the rungs of the society. This could be mostly due to our evading the very subject of death much owing to the general uneasiness, fear and a sort of psychological insecurity, while dealing with it. Therefore it is always easy to raise philosophical questions than to answer them. There are almost two dozen theories in vogue which have certain basic assumptions but somehow they do not fall in the domain of truly scientific inquiry. They are to be accepted as an outcome of religious sentiments or wishful thinking. This paper highlights the salient features of Indian philosophical viewpoint with regard to death.
I wear Prada, because I want to.
Authors: Richards-Carpenter Nastaran Norouzi
Published: October 2017

: Previous studies on luxury consumption indicated that women may use luxury consumption as a self-promotion strategy during within-sex competitions, as these luxuries improve their advantages against same sex rivals for mates. Many of these studies rely on costly signalling and intra-sexual competition theory, and they suggest female intra-sexual competition in a mate attraction context triggers women’s spending on luxury products. The focus of this paper is to understand the gender-related motivations, specifically for female consumers in the luxury market and to compare and contrast the new findings with the previous studies. The finding of this study demonstrates other motives in female luxury consumer behaviour rather than relationship, self-enhancement and competition.

The Lexicon of Development: A Quantitative History of the Language of Development Studies
Authors: Absell Christopher David
Published: October 2017

The objective of this article is to examine the history of the language of development theory in order to elucidate the nature of its terminology. The history of the principal terms of development theory (economic/sustainable/human development, Third World, and North/(Global) South) is examined by way of a quantitative study of the frequency of the usage of these terms during the 20th century based on a dataset of millions of digitised books made available by Google Books. The author argues that the results of the study provide empirical evidence that the language of development theory is a historical-ideological construction which is embedded in the structure of the world economy.
Rights of nature and the indigenous peoples in Bolivia and Ecuador: A Straitjacket for Progressive Development Politics?
Authors: Lalander Rickard
Published: October 2017

Is it possible to justify resource extractivism to provide progressive welfare politics and still respect the constitutional rights of nature? The Indigenous concept of Sumak Kawsay on human beings living in harmony with each other and the environment is the fundamental framing of the new constitutions of Ecuador and Bolivia. These constitutional reforms embrace strengthened proper rights of nature and similarly of ethnic rights. However, the same constitutions grant the State the right to exploit and commercialize natural resources and extractivism has increased. This study revises the tensions between welfare politics, extractivism and the rights of nature and the Indigenous peoples in the new constitutional settings of Bolivia and, particularly, Ecuador. The article argues that Sumak Kawsay challenges dominating understandings of the concepts of welfare, common good and development, and likewise that a pragmatic approach is applied by national governments towards the constitutional rights of nature amidst other human values.
Subjective dimension in the analysis of human development
Authors: Domínguez-Martín Rafael , López-Noval Borja
Published: October 2017

In recent years subjective evaluations about own quality of life, resumed in levels of life satisfaction or happiness, are gaining importance as indicators of development. Some authors state that subjective well-being is a necessary and sufficient condition for human development. In this work the arguments ofthese authors are explained and it is discussed the role subjective evaluations must play on development studies. The main conclusion is that although it is necessary to integrate subjective well-being into humandevelopment studies we cannot identify subjective well-being and development.CITE AS:Domínguez-Martín, R., López-Noval, B.

Middle income countries? An alternative development taxonomy of Latin America and the Caribbean
Authors: Tezanos-Vázquez Sergio , Quiñones-Montellano Ainoa
Published: October 2017

Although it is not asy to classify countries according to their levels of development –mainly because the concept of “human development” is complex and multidimensional –, the most widespread classification is just the simplest one, based on income per capita levels. According to this classification, most of the Latin America and the Caribbean (LAC) countries are located in the world middle-income strata. This paper proposes an alternative “development taxonomy” for LAC middle-income countries. Using a cluster analysis we identify and characterize three groups of countries in relation to 10 main “development gaps”: the most advanced countries (Mexico, Chile, Argentina, Venezuela, Uruguay and Brasil), the middle-development countries (Panama, Costa Rica, Colombia, Jamaica, Dominican Republic, Ecuador, Peru, Belize, El Salvador, Paraguay and Guyana) and those countries with the greatest development challenges (Guatemala, Bolivia, Honduras and Nicaragua).CITE AS:Tezanos-Vázquez, S., Quiñones-Montellano, A.

Anacronismos. 1958, el proyecto de Jorge Oteiza para el monumento a José Batlle en Montevideo | Anachronisms. 1958, Jorge Oteiza’s project for the Monument to Jose Batlle in Montevideo
Authors: Marín Antonio
Published: October 2017

El proyecto que Jorge Oteiza presentó en 1958 al concurso para el Monumento a José Batlle en Montevideo suponía, según sus propias palabras, su trabajo final dentro de la investigación experimental sobre la naturaleza espacial de la escultura. Justo antes de empezar a trabajar en el proyecto, había realizado sus primeras conclusiones experimentales, había llevado a cabo el razonamiento estético sobre el crómlech-estatua y había elaborado el concepto teórico con el que plantear la integración de arte y arquitectura a escala urbana, la nueva monumentalidad. Si a alguna de sus esculturas conclusivas la había titulado mueble metafísico, al modelo de integración, arquitectura+(arte = 0), a escala urbana lo denominó aislador metafísico. Basado en la desocupación espacial, proponía la delimitación de grandes vacíos activos en el interior del complejo urbano, aisladores metafísicos de la circunstancia vital, para que el habitante de la ciudad pudiera relajar el estado de alerta permanente de sus capacidades perceptivas, para la toma de conciencia estética del espacio como acto de libertad individual. Si bien su proyecto respondía al desarrollo lógico de su propósito experimental personal, apareció en el momento histórico equivocado. Ni las circunstancias acompañaron, ni estaba preparada la sensibilidad general para una propuesta que se adelantaba, formal y teóricamente, a algunas de las ideas que pocos años después dirigirían los comportamientos en el arte. Era, pues, un anacronismo.The project Jorge Oteiza presented in 1958 to the competition for the Monument to Jose Batlle in Montevideo supposed, in his own words, his final work in the experimental research on the spatial nature of sculpture. Just before starting to work on the project, he had made his first experimental conclusions, had carried out his aesthetic reasoning about the cromlech-statue and had developed the theoretical concept with which to set the integration of art and architecture on an urban scale, the new monumentality. If he had entitled any of his concluding sculptures as Metaphysical Box, the integration model he proposed, architecture + (Art=0), on an urban scale was named the Metaphysical Insulator. Based on his concept of the spatial disoccupation, it proposed the demarcation of large charged voids within the urban complex, metaphysical insulators for the vital circumstance where the city dweller could relax the state of permanent alert of his perceptual capacities, for the aesthetic awareness-raising of space as an act of individual freedom. While his project reflected the logical development of his personal experimental purposes, it appeared in the wrong historical time. Nor the circumstances accompanied nor the overall sensitivity was prepared to a proposal that anticipated, both formally and theoretically, some of the ideas that a few years later would lead the behavior in art. It was, therefore, an anachronism.

El litoral español: más de un cuarto de siglo a la deriva | The Spanish coast: more than a quarter of a century adrift
Authors: García García Miriam
Published: October 2017

Aún bajo los efectos de la resaca de la más intensa crisis financiera e inmobiliaria sufrida en España, que ha dejado en las costas españolas un paisaje malherido, se bucea en sus raíces. Para ello se hace necesario remontarse a los orígenes y la posterior evolución del marco legal que regula en la protección del litoral y la planificación urbanística. Todo ello en un contexto político y socio económico que, como se verá, ha encontrado en la legislación urbanística y en la esquelética ordenación territorial la necesaria complicidad para la devastación de una gran parte del sistema litoral. Y es que a pesar de que en nuestros días la práctica totalidad de las regiones litorales de España cuentan con alguna figura de protección y ordenación de sus costas, su alcance es claramente insuficiente e incoherente con el contexto global del cambio climático y la demanda social creciente de un paisaje que tenga sentido desde el punto de vista de su funcionalidad ecológica y capacidad de uso social.PALABRAS CLAVE: Litoral, costa, planificación territorial, cambio climático, paisaje.Still under the effects of the hangover of the most intense financial and real estate crisis suffered in Spain, which has left on the Spanish coast a badly damaged landscape, its roots are investigated. For this, it is necessary to go back to the origins and the subsequent evolution of the legal framework that regulates in the country the protection of the coast and urban planning. All this in a political and socio-economic context that, as will be seen, has found in urban planning legislation and in the skeletal territorial planning of the coast the necessary complicity for the devastation of a large part of the coastal system. Despite the fact that, in our time, practically all the coastal regions of Spain have some instrument of protection and management of their coasts, their scope is insufficient and inconsistent with the global context of climate change and the growing social demand for a landscape that makes sense from the point of view of its ecological functionality and capacity for social use.KEYWORDS: Coastline, coast, territorial planning, climate change, landscape.

Authors: Alam Md Zahid , Rahman Aparna , Hoque Shabnam Jahan , Irfan SM Rezaul , Miah Md Babul , Hossain Mohammad Shakhawat
Published: October 2017

Background: Dyslipidemia is one of the main risk factors with prognostic significance in relation to coronary heart disease. Aggressive treatment has been recommended in acute coronary syndrome (ACS). We examined pattern of dyslipidemia in ST Elevation myocardial infarction (STEMI) and Non- ST elevation myocardial infarction (NSTEMI). We also compare the lipid status in between two types of myocardial infarction (MI).Methods: This cross sectional observational study was carried out enrolling 100 subjects with ST elevation and Non ST elevation Myocardial Infarction, in the Department of Cardiology, BIRDEM General Hospital, Shahbag, Dhaka, over a period of six months from January 2012 to June 2012. Fasting lipid profile was done in next morning of admission in both type of MI.Results: Mean age and gender difference was significant between STEMI and NSTEMI. Mean Cholesterol (chol), Triglyceride (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL) were not statistically significant between male and female groups. All mean cholesterol, TG, HDL, LDL were significantly high in older age group. The Mean cholesterol (220.7±28.1Vs208.4±20.9), triglyceride (182.8±34.4 Vs 147.4±28.9), HDL (35.14±5.7 Vs 41.65±3.8) and LDL (160.7±26.2 Vs148.3±16.8)were also statistically significant between STEMI and NSTEMI groups (p<0.05).Conclusion: Dyslipidemia is the dominating coronary risk factors. It could be concluded that significant differences are observed between two types of MI. Lipid status is relatively more uncontrolled in ST elevated MI and must be managed with all possible therapeutic modules to minimize further complications.Bangladesh Crit Care J September 2017; 5(2): 106-109

It also facilitates the evaluation of response to therapeutic intervention. This review examines the potential applications of functional echocardiography in different disease states, and how the technology may be introduced safely in the NICU.Cardiovasc. j. 2017; 10(1): 74-83
Effects of the Amount and Type of Diol Ring Openers on the Properties of Oligolactide Acrylates for UV-Curable Printing Inks
Authors: Kulsiriswad Santi , Srikulkit Kawee , Saravari Onusa
Published: October 2017

This study aimed to synthesize low viscosity oligolactide acrylates for UV-curable inks from oligolactide diols. Firstly, low molecular weight oligolactide diols were prepared by ring opening reaction of L-lactide with diols. Oligolactide acrylates were then synthesized by functionalizing the oligolactide diols with acrylic acid. In this study, three diol ring openers having short and long alkyl chain length were used to investigate the effects of the amount and type of diols on the properties of the oligolactide acrylates. The obtained oligomers were characterized, and the viscosities of oligolactide acrylates were measured. Results showed that oligolactide acrylates were successfully synthesized in all cases of ring openers, as confirmed by 1H-NMR (proton nuclear magnetic resonance spectroscopy) and FTIR (Fourier transform infrared spectroscopy). An increase in the alkyl chain length of the ring openers resulted in oligomers with lower viscosity and a decrease in Tg. Following that, the obtained oligolactide acrylates were employed for the formulation of UV-curable screen printing inks and their properties were investigated. Results showed that the inks formulated from oligomers with lower molecular weight exhibited better ink flow. Additionally, all ink films cured by UV radiation were very flexible with excellent adhesion, high impact resistance, and excellent water resistance.
Synchrotron Radiation Pair Distribution Function Analysis of Gels in Cements

Published: October 2017

The analysis of atomic ordering in a nanocrystalline phase with small particle sizes, below 5 nm, is intrinsically complicated because of the lack of long-range order. Furthermore, the presence of additional crystalline phase(s) may exacerbate the problem, as is the case in cement pastes. Here, we use the synchrotron pair distribution function (PDF) chiefly to characterize the local atomic order of the nanocrystalline phases, gels, in cement pastes. We have used a multi r-range analysis approach, where the ~4–7 nm r-range allows determining the crystalline phase contents; the ~1–2.5 nm r-range is used to characterize the atomic ordering in the nanocrystalline component; and the ~0.2–1.0 nm r-range gives insights about additional amorphous components. Specifically, we have prepared four alite pastes with variable water contents, and the analyses showed that a defective tobermorite, Ca11Si9O28(OH)2.8.5H2O, gave the best fit. Furthermore, the PDF analyses suggest that the calcium silicate hydrate gel is composed of this tobermorite and amorphous calcium hydroxide. Finally, this approach has been used to study alternative cements. The hydration of monocalcium aluminate and ye’elimite pastes yield aluminum hydroxide gels. PDF analyses show that these gels are constituted of nanocrystalline gibbsite, and the particle size can be as small as 2.5 nm.

Published: October 2017

We develop a new model where the dynamic structure of the asset price, after the fundamental value is removed, is subject to two different regimes. One regime reflects the normal period where the asset price divided by the dividend is assumed to follow a mean-reverting process around a stochastic long run mean. The second regime reflects the bubble period with explosive behavior. Stochastic switches between two regimes and non-constant probabilities of exit from the bubble regime are both allowed. A Bayesian learning approach is employed to jointly estimate the latent states and the model parameters in real time. An important feature of our Bayesian method is that we are able to deal with parameter uncertainty and at the same time, to learn about the states and the parameters sequentially, allowing for real time model analysis. This feature is particularly useful for market surveillance. Analysis using simulated data reveals that our method has good power properties for detecting bubbles. Empirical analysis using price-dividend ratios of S&P500 highlights the advantages of our method.

Optical beam has been the veteran inspector of semiconductor wafer production house, ever since the birth of integrated circuit (IC). As technology and market place raise the bar on chip density, Moore’s law stretches to the limit. Due to its inherent physical limitations, the optical method just cannot see the measuring rod of silicon industry getting recalibrated to finer nano-scales. Electron Beam Inspection (EBI), by virtue of its high resolution, has started to rule the nodes at 10 nm and below. As the geometries shrink, defects can reside deep within the structures. EBI can find those tiny defects, which otherwise go scot-free with optical tools. However, EBI suffers the handicap of poor performance and low throughput. It is therefore essential to complement EBI by judiciously crafting out the methods for getting the desired performance, a subject matter to which, this article is committed to. The research torchlights the critical EBI throughput problem to round-up “care-areas”. Such guided and focused inspection augments throughput, thereby positioning EBI as the industrial grade candidate in finer nanometer segment. Besides gearing up to current trends, the smart EBI school of thought is inspirational, to fuel the aspirations for 1 nanometer scale.

Due to environmental concerns, economic issues, and emerging new loads, such as electrical vehicles (EVs), the importance of demand side management (DSM) programs has increased in recent years. DSM programs using a dynamic real-time pricing (RTP) method can help to adaptively control the electricity consumption. However, the existing RTP methods, particularly when they consider the EVs and the power system constraints, have many limitations, such as computational complexity and the need for centralized control. Therefore, a new transactive DSM program is proposed in this paper using an imperfect competition model with high EV penetration levels. In particular, a heuristic two-stage iterative method, considering the influence of decisions made independently by customers to minimize their own costs, is developed to find the market equilibrium quickly in a distributed manner. Simulations in the IEEE 37-bus system with 1141 customers and 670 EVs are performed to demonstrate the effectiveness of the proposed method. The results show that the proposed method can better manage the EVs and elastic appliances than the existing methods in terms of power constraints and cost. Also, the proposed method can solve the optimization problem quick enough to run in real-time.

Vehicle models whose propulsion system is based on electric motors are increasing in number within the automobile industry. They will soon become a reliable alternative to vehicles with conventional propulsion systems. The main advantages of this type of vehicles are the non-emission of polluting gases and noise and the effectiveness of electric motors compared to combustion engines. Some of the disadvantages that electric vehicle manufacturers still have to solve are their low autonomy due to inefficient energy storage systems, vehicle cost, which is still too high, and reducing the recharging time. Current regenerative systems in motorcycles are designed with a low fixed maximum regeneration rate in order not to cause the rear wheel to slip when braking with the regenerative brake no matter what the road condition is. These types of systems do not make use of all the available regeneration power, since more importance is placed on safety when braking. An optimized regenerative braking strategy for two-wheeled vehicles is described is this work. This system is designed to recover the maximum energy in braking processes while maintaining the vehicle’s stability. In order to develop the previously described regenerative control, tyre forces, vehicle speed and road adhesion are obtained by means of an estimation algorithm. A based-on-fuzzy-logic algorithm is programmed to carry out an optimized control with this information. This system recuperates maximum braking power without compromising the rear wheel slip and safety. Simulations show that the system optimizes energy regeneration on every surface compared to a constant regeneration strategy.
Predictions of Surface Solar Radiation on Tilted Solar Panels using Machine Learning Models: A Case Study of Tainan City, Taiwan
Authors: Wei Chih-Chiang
Published: October 2017

In this paper, forecasting models were constructed to estimate surface solar radiation on an hourly basis and the solar irradiance received by solar panels at different tilt angles, to enhance the capability of photovoltaic systems by estimating the amount of electricity they generate, thereby improving the reliability of the power they supply. The study site was Tainan in southern Taiwan, which receives abundant sunlight because of its location at a latitude of approximately 23°. Four forecasting models of surface solar irradiance were constructed, using the multilayer perceptron (MLP), random forests (RF), k-nearest neighbors (kNN), and linear regression (LR), algorithms, respectively. The forecast horizon ranged from 1 to 12 h. The findings are as follows: first, solar irradiance was effectively estimated when a combination of ground weather data and solar position data was applied. Second, the mean absolute error was higher in MLP than in RF and kNN, and LR had the worst predictive performance. Third, the observed total solar irradiance was 1.562 million w/m2 per year when the solar-panel tilt angle was 0° (i.e., the non-tilted position) and peaked at 1.655 million w/m2 per year when the angle was 20–22°. The level of the irradiance was almost the same when the solar-panel tilt angle was 0° as when the angle was 41°. In summary, the optimal solar-panel tilt angle in Tainan was 20–22°.

Published: October 2017

This paper presents a novel approach for providing a mobile battery swapping service for electric vehicles (EVs) that is provided by a mobile battery swapping van. This battery swapping van can carry many fully charged batteries and drive up to an EV to swap a battery within a few minutes. First, a reasonable EV battery swapping architecture based on a battery swapping van is established in this paper. The function and role of each participant and the relationships between each participant are determined, especially their changes compared with the battery charging service. Second, the battery swapping service is described, including the service request priority and service request queuing model. To provide the battery swapping service efficiently and effectively, the battery swapping service request scheduling is analyzed well, and a minimum waiting time based on priority and satisfaction scheduling strategy (MWT-PS) is proposed. Finally, the battery swapping service is simulated, and the performance of MWT-PS is evaluated in simulation scenarios. The simulation results show that this novel approach can be used as a reference for a future system that provides reasonable and satisfying battery swapping service for EVs.

The impacts of laser radiation (Nd: YAG laser, 1064 nm at 800 mW, He–Ne laser 808 nm at 6 W, semiconductor laser 632.8 nm at 40 mW) on growth and lipid accumulation of Chlorella pacifica were investigated in this study. The results showed growth rates increased 1.23, 1.41, and 1.40-fold over controls by 4 min Nd: YAG, 4 min He–Ne, and 8 min semiconductor laser treatments, respectively, whereas the corresponding nitrate reductase observed increased 1.25, 1.63, and 2.08-fold over controls. Moreover, total chlorophyll concentration was increased to 1.09, 1.29, and 1.33-fold over controls, respectively. After 20 days cultivation, the highest lipid content was 35.99%, 18.46%, and 31.00% after 2 min Nd: YAG, 4 min He–Ne, and 4 min semiconductor laser treatments, corresponding to 2.86, 1.50, and 2.46-fold increase over controls, respectively. Furthermore, the lipid productivity of the above 3 treatments were 15.25 ± 2.56, 16.25 ± 2.45, and 14.75 ± 2.11 mg L−1 d−1. However, the highest lipid productivity was 22.00 ± 3.28, 16.25 ± 2.45, and 19.25 ± 1.78 mg L−1 d−1, in response to treatment for 2 min Nd: YAG, 1 min He–Ne, and 4 min semiconductor laser treatments, with 2.67, 1.97, and 2.33-fold increase over controls, respectively. These results indicated that lipid accumulation efficiency of C. pacifica could be significantly improved by laser irradiation using Nd: YAG, He–Ne, and semiconductor laser treatments.

With the growth of renewable generated electricity in the energy mix, large energy storage and flexible demand, particularly aggregated demand response is becoming a front runner as a new participant in the wholesale energy markets. One of the biggest barriers for the integration of aggregator services into market participation is knowledge of the current and future flexible capacity. To calculate the available flexibility, the current aggregator pilot and simulation implementations use lower level measurements and device specifications. This type of implementation is not scalable due to computational constraints, as well as it could conflict with end user privacy rights. Black box machine learning approaches have been proven to accurately estimate the available capacity of a cluster of heating devices using only aggregated data. This study will investigate the accuracy of this approach when applied to a heterogeneous virtual power plant (VPP). Firstly, a sensitivity analysis of the machine learning model is performed when varying the underlying device makeup of the VPP. Further, the forecasted flexible capacity of a heterogeneous residential VPP was applied to a trade strategy, which maintains a day ahead schedule, as well as offers flexibility to the imbalance market. This performance is then compared when using the same strategy with no capacity forecasting, as well as perfect knowledge. It was shown that at most, the highest average error, regardless of the VPP makeup, was still less than 9%. Further, when applying the forecasted capacity to a trading strategy, 89% of the optimal performance can be met. This resulted in a reduction of monthly costs by approximately 20%.
