description: The state of Palestine, whose total land is around 6020 square kilometers (Worldometer, 2021), consists of two developing areas: The West Bank and the Gaza Strip. The rest of Palestine is controlled by the Israeli occupation. The Israeli occupation that was imposed on the land decades ago since 1948 has burdened the country with deteriorating economic situation of unbearable poverty and extraordinary unemployment rates, pushing Palestinians to find original mechanisms to sustain their basic needs. In particular, Palestinian women’s lifestyles have been profoundly challenged, where particular gender roles change to cope with the current harsh circumstances. Focusing on the geographically-restricted area of the Gaza Strip that has been suffering from an Israeli-Egyptian blockade since 2006, the objective of this study is to bring Palestinian women from the Gaza Strip to the center of a discussion about the gendered dimensions of women’s utilization of social media to launch private enterprises within a patriarchal society occupied by the Israeli occupation to sustain the needs of themselves and their families. A few studies have been carried out on women’s utilization of social media to start-up businesses within the context of the Gaza Strip. Three factors will be tackled throughout the analysis: challenging the social norms and patriarchy within the Gazan society, challenging the blockade of the Israeli occupation, and the novel use of social media platforms by Gazan women in starting-up their own enterprises to challenge both patriarchy and occupation. Four Gazan women entrepreneurs were interviewed to collect data that was qualitatively analyzed. Based on the analysis, the study concluded that the gender roles within the Gazan society are changing due to the high rates of unemployment and poverty, where many Gazan women occupy social media platforms using their own talents and hobbies to start businesses to help support their families. The findings of this study not only add to the feminist literature, but it also gives voices to some creative Gazan women, and gives insights to any business associations either within the Palestinian context or the international context on the different fields where Gazan women can achieve success, opening up new opportunities to the women in question.

description: Black holes with masses of $\rm 10^6-10^9~M_{\odot}$ dwell in the centers of most galaxies, but their formation mechanisms are not well known. A subdominant dissipative component of dark matter with similar properties to the ordinary baryons, known as mirror dark matter, may collapse to form massive black holes during the epoch of first galaxies formation. In this study, we explore the possibility of massive black hole formation via this alternative scenario. We perform three-dimensional cosmological simulations for four distinct halos and compare their thermal, chemical and dynamical evolution in both the ordinary and the mirror sectors. We find that the collapse of halos is significantly delayed in the mirror sector due to the lack of $\rm H_2$ cooling and only halos with masses above $ \rm \geq 10^7~ M_{\odot}$ are formed. Overall, the mass inflow rates are $\rm \geq 10^{-2}~M_{\odot}/yr$ and there is less fragmentation. This suggests that the conditions for the formation of massive objects, including black holes, are more favorable in the mirror sector.

A Study of the Digital Identity Performance of Qatari Women in Social Networks

description: In recent times, research has been undertaken to examine the performance of digital identity in the context of social networks. However, hardly any research on this topic appears to focus on the performance of women’s digital identities in the Qatari context. Thus, this thesis aims to critically analyze the significance of the phenomenon of Qatari women’s digital performance of identities in the light of restrictive socio-cultural traditions, gender stereotypes, and anonymity. The first research question examined the extent to which the restrictive Qatari society and domestic violence have influenced Qatari women’s digital performance of identities, while the second examined whether gender stereotypes imply limitations on Qatari women’s digital performance of identities. The third research question analyzed the implications of anonymity on Qatari women’s digital performance of identity authenticity. This study used a qualitative interviewing method to generate an in-depth understanding of this phenomenon. A total of twelve Qatari women were interviewed. The findings indicate that Qatari women’s experiences of restrictive socio-cultural norms and traditions, domestic violence, and abuse influence their digital performance of identities and that they use social networks as mediums for creative self-expression, advocacy, and raising awareness. However, the findings also suggest that societal gender stereotypes have transmitted to the digital environment, thus limiting Qatari women’s opportunities for self-expression. As a result, Qatari women hide their identities in an attempt to free themselves from any restrictive boundaries. Despite securing the freedom to self-express, the findings indicate that anonymity is problematic to Qatari women’s identities because the self becomes so blurred that it no longer recognizes its authentic self. These findings suggest that Qatari women are living in a hyperreality where reality no longer exists. Thereby, this thesis implies that there is no true authentic self but an essence of self that people aspire to.

description: Recent work on gravitational geons is extended to examine the stability properties of gravitational and electromagnetic geon constructs. All types of geons must possess the property of regularity, self-consistency and quasi-stability on a time-scale much longer than the period of the comprising waves. Standard perturbation theory, modified to accommodate time-averaged fields, is used to test the requirement of quasi-stability. It is found that the modified perturbation theory results in an internal inconsistency. The time-scale of evolution is found to be of the same order in magnitude as the period of the comprising waves. This contradicts the requirement of slow evolution. Thus not all of the requirements for the existence of electromagnetic or gravitational geons are met though perturbation theory. From this result it cannot be concluded that an electromagnetic or a gravitational geon is a viable entity. The broader implications of the result are discussed with particular reference to the problem of gravitational energy.

description: Linear-optical systems can implement photonic quantum walks that simulate systems with nontrivial topological properties. Here, such photonic walks are used to jointly entangle polarization and winding number. This joint entanglement allows information processing tasks to be performed with interactive access to a wide variety of topological features. Topological considerations are used to suppress errors, with polarization allowing easy measurement and manipulation of qubits. We provide three examples of this approach: production of two-photon systems with entangled winding number (including topological analogs of Bell states), a topologically error-protected optical memory register, and production of entangled topologicallyprotected boundary states. In particular it is shown that a pair of quantum memory registers, entangled in polarization and winding number, with topologically-assisted error suppression can be made with qubits stored in superpositions of winding numbers; as a result, information processing with winding number-based qubits is a viable possibility.

description: We describe the nature of charge transport at non-zero temperatures ($T$) above the two-dimensional ($d$) superfluid-insulator quantum critical point. We argue that the transport is characterized by inelastic collisions among thermally excited carriers at a rate of order $k_B T/\hbar$. This implies that the transport at frequencies $ω\ll k_B T/\hbar$ is in the hydrodynamic, collision-dominated (or `incoherent') regime, while $ω\gg k_B T/\hbar$ is the collisionless (or `phase-coherent') regime. The conductivity is argued to be $e^2 / h$ times a non-trivial universal scaling function of $\hbar ω/ k_B T$, and not independent of $\hbar ω/k_B T$, as has been previously claimed, or implicitly assumed. The experimentally measured d.c. conductivity is the hydrodynamic $\hbar ω/k_B T \to 0$ limit of this function, and is a universal number times $e^2 / h$, even though the transport is incoherent. Previous work determined the conductivity by incorrectly assuming it was also equal to the collisionless $\hbar ω/k_B T \to \infty$ limit of the scaling function, which actually describes phase-coherent transport with a conductivity given by a different universal number times $e^2 / h$. We provide the first computation of the universal d.c. conductivity in a disorder-free boson model, along with explicit crossover functions, using a quantum Boltzmann equation and an expansion in $ε=3-d$. The case of spin transport near quantum critical points in antiferromagnets is also discussed. Similar ideas should apply to the transitions in quantum Hall systems and to metal-insulator transitions. We suggest experimental tests of our picture and speculate on a new route to self-duality at two-dimensional quantum critical points.

Factors impacting length of stay for Medicare patients 65 years and older diagnosed with sepsis

Year: 2021

description: Purpose of Project: This study aims to explore if APN-led transitional care reduces the length of stay (LOS) during transitional care from the acute care setting to an alternative care setting for Medicare patients 65 years and older diagnosed with sepsis. Methodology: The study was designed as a descriptive statistic through a retrospective chart review in a teaching hospital in Northern New Jersey. The study sample of 104 charts randomly selected. Results: The mean LOS for males was 11.20 days, and for females 11.28 days. The mean LOS for sepsis was 9.20, severe sepsis 9.83, and septic shock 19.39. There were the differences of p-values in outcomes of LOS based on variables of interest: the p-value for age was 0.149, for gender 0.648, for race 0.862, diagnosis 0.432, and comorbidities 0.163.Implications for Practice: In this study, the cases that had APN involvement during transitional care and the patient’s community support system were too small to perform a statistical test of the association with LOS. However, the patient’s age (p = 0.149), comorbidities (p = 0.163), and diagnosis (p = 0.432) were associated with patients’ LOS. Yet, these factors were not statistically significant. Therefore, this study was not able to conclude that the APN involvement during transitional care was the key factor in reducing LOS in this study setting.
Spin Dynamics of the One-Dimensional J-J' Model and Spin-Peierls Transition in CuGeO_3

description: Spin dynamics as well as static properties of the one-dimensional J-J' model (S=1/2, J>0 and 0\le α=J'/J\le 0.5) are studied by the exact diagonalization and the recursion method of finite systems up to 26 sites. Especially, the dynamical structure factor S(q,ω) is investigated carefully for various values of α. As αincreases beyond the gapless-gapful critical value α_c=0.2411, there appear features definitely different from the Heisenberg model but the same with the Majumdar-Ghosh model. Some of these features depend only on the value of αand not on δ: a parameter introduced for the coupling alternation. By comparing these results with a recent inelastic neutron scattering spectrum of an inorganic spin-Peierls compound CuGeO_3 [M. Arai et al.: Phys. Rev. Lett. 77 (1996) 3649], it is found that the frustration by J' in CuGeO_3 is unexpectedly strong (α=0.4-0.45), and at least αmust be larger than α_c to some extent. The value of J is evaluated at \sim 180K consistent with other estimations. The coupling alternation is extremely small. This large frustration is a primary origin of the various anomalous properties CuGeO_3 possesses. For comparison we refer also to α'-NaV_2O_5.

Creators: name: Olajide Abolarin, M
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 1981

description: Patterns of parasitaemia of rodent bloodstream trypanosomes were studied on agar with phase-contrast microscopy (agar technique). The parasites were three strains of Trypanosoma hrucei rhodesiense isolated from man in Botswana and Zambia. The parasitaemias in the normal and immunodepressed rats were oleomorphic. In all the three strains the patterns of parasitaemia were transiently enhanced by dexamethasone acetate but the enhancement exhibited when total body x-irradiation was applied was sustained. The superiority of the agar technique over the length-measurement methods in assessing pleomorphism is indicated. Light microscopy showed the possibilities of characterisation of animal and human species of African trypanosomiasis. This was based on the number, location and distribution of the biochemically stable linoprotein granules. Scanning electron microscopy illustrated details of the various forms of vascular trypanosomes of medical and veterinary importance. The existence, characteristics and relationship of the cylindrica 1 lv-shaped long-narrow trypanosome is discussed in contrast to the characteristics of the other major flat-looking forms. The appendages or filaments associated with the different forms are also exhibited. Stages of in vivo as well as in vitro phago-cvtosis of T.h. rhodesiense by peritoneal macrophages were also observed by scanning electron microscopy. Salicylhydroxamic acid in conjunction with glycerol was used to clear the blood of trypanosomes. The new populations were shown to be agranular in form and some of these were long-narrow. Observation on tsetse- transmitted infections and on the bloodstream culture forms showed that the first wave of parasites were agranular but no long-narrow forms could be identified. Forms from the peritoneal fluid in rats and ascites tumour fluid in mice were found to be pleomorphic. These included the giant forms of multinuclear, multi- flagellar and multikinetoplastic types. The roundbodied trypanosomes found in these fluids are related to those found in the vascular system while the multinuclear forms in the fluids are similar to those in the tissues. The tissue forms of Botswana strain of T.b. rhodesiense were studied by electron transmission microscopy. Some parasites located in the choroid plexus of SHAM-treated and untreated rats were discovered to be intracellular. The implication of this discovery in relation to life- cycle, pathology and chemotherapy is outlined.

description: For the unbalanced one-way random effects model with heterogeneous error variances, we propose the non-informative priors for the between-group variance and develop the first- and second-order matching priors. It turns out that the second-order matching priors do not exist and the reference prior and Jeffreys prior do not satisfy a first-order matching criterion. We also show that the first-order matching prior meets the frequentist target coverage probabilities much better than the Jeffreys prior and reference prior through simulation study, and the Bayesian credible intervals based on the matching prior and reference prior give shorter intervals than the existing confidence intervals by examples.
title: The Use of Serology and Of Tests for Drug And Insecticide Resistance in tudying Problems Of Malaria Control in the Sudan
Creators: name: Akood, MAS
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 1980

description: This thesis describes the application of new malariological techniques to study some of the problems facing, or which might face, the malaria control programme in The Gezira (Blue Nile Province) of The Sudan. Serological tests, using the indirect fluorescent antibody test were carried out on a large sample of the population of the Gezira in 1977 and 1979 drawn from 18 localities in 4 different areas. The results showed a much higher level of prevalence and incidence of malaria than was detected by routine parasitological examinations. The percentage of those who had positive antibody reactions decreased in 1979 from that of 1977 in North, West, and South Gezira, but in Central Gezira there was a significant rise from 27% to 75%, indicating the presence of a high level of transmission. This coincided with malathion resistance of the vector in this area. Eggs from females of Anopheles arabiensis, the main malaria vector there, which had survived field tests on malathion were brought to London and reared for further testing and genetic studies. A population which survived exposure to 5% malathion for S hours was selected. Crossing and backcrossing of this population with three different malathion-susceptible populations of A. arabiensis showed an involvement of one gene in the resistance, which appeared to be of dominant nature. Tests with Fenitrothion, Fenthion, and Propoxur gave total kills, showing no signs of cross-resistance. There was no indication of resistance to Malathion or to Temephos (Abate) at the larval stages. The spread of drug resistant human malaria parasites is a possible danger for the future of malaria control in Africa. A micro in vitro test for drug resistance was developed using rodent and primate malaria parasites as model5, as well as blood from human malaria cases in London. Radioactive chloroquine was used in a social study to estimate the adsorption of low concentrations of the drug to plastic and glass vials which might affect the results of the micro test. Approximately 20% loss was observed. A limited field trial of the micro-test in the Sennar Area (Blue Nile Province) showed no clear indication of drug resistance at the present time. These results confirmed those of in vivo tests done at the same time.

description: $^{13}$CO molecules are intercalated under a single layer graphene film on Ru(0001) and interrogated with helium low energy ion scattering. Single scattering is used to determine the mass distribution of atomic species visible to the ion beam and detector, and the scattering angle is varied to distinguish adsorbed from intercalated molecules. At room temperature, CO intercalates as molecules that sit upright with the O end on top, as on clean Ru. The intercalated CO tilts, more than it does on clean Ru, when the temperature is raised. This is presumably due to increased vibrational amplitudes combined with the confining effect of the graphene film.

The geometry, as studied using invariants, has the topology of wormholes found in (3+1) gravity. In the induced-matter picture, the fluid does not satisfy the strong energy conditions, but its gravitational mass is positive. We infer the possible existance of (4+1) wormholes which, compared to their (3+1) counterparts, are less exotic.

description: © 2020 The Author(s). Background: Alcohol affects Indigenous communities globally that have been colonised. These effects are physical, psychological, financial and cultural. This systematic review aims to describe the prevalence of current (12-month) alcohol dependence in Indigenous Peoples in Australia, New Zealand, Canada and the United States of America, to identify how it is measured, and if tools have been validated in Indigenous communities. Such information can help inform estimates of likely treatment need. Methods: A systematic search of the literature was completed in six electronic databases for reports on current alcohol dependence (moderate to severe alcohol use disorder) published between 1 January 1989-9 July 2020. The following data were extracted: (1) the Indigenous population studied; country, (2) prevalence of dependence, (3) tools used to screen, assess or diagnose current dependence, (4) tools that have been validated in Indigenous populations to screen, assess or diagnose dependence, and (5) quality of the study, assessed using the Appraisal Tool for Cross-Sectional Studies. Results: A total of 11 studies met eligibility criteria. Eight were cross-sectional surveys, one cohort study, and two were validation studies. Nine studies reported on the prevalence of current (12-month) alcohol dependence, and the range varied widely (3.8-33.3% [all participants], 3-32.8% [males only], 1.3-7.6% [females only]). Eight different tools were used and none were Indigenous-specific. Two tools have been validated in Indigenous (Native American) populations. Conclusion: Few studies report on prevalence of current alcohol dependence in community or household samples of Indigenous populations in these four countries. Prevalence varies according to sampling method and site (for example, specific community versus national). Prior work has generally not used tools validated in Indigenous contexts. Collaborations with local Indigenous people may help in the development of culturally appropriate ways of measuring alcohol dependence, incorporating local customs and values. Tools used need to be validated in Indigenous communities, or Indigenous-specific tools developed, validated and used. Prevalence findings can inform health promotion and treatment needs, including funding for primary health care and specialist treatment services.

description: We focus on various measures of the fluctuations of the sequence of intervals between beats of the human heart, and how such fluctuations can be used to assess the presence or likelihood of cardiovascular disease. We examine sixteen such measures and their suitability for correctly classifying heartbeat records of various lengths as normal or revealing the presence of cardiac dysfunction, particularly congestive heart failure. Using receiver-operating-characteristic analysis we demonstrate that scale-dependent measures prove substantially superior to scale-independent ones. The wavelet-transform standard deviation at a scale near 32 heartbeat intervals, and its spectral counterpart near 1/32 cycles/interval, turn out to provide reliable results using heartbeat records just minutes long. We further establish for all subjects that the human heartbeat has an underlying stochastic origin rather than arising from a chaotic attractor. Finally, we develop a mathematical point process that emulates the human heartbeat time series for both normal subjects and heart-failure patients.

description: The technique of mutual approximations accurately gives the central instant at the maximum apparent approximation of two moving natural satellites in the sky plane. This can be used in ephemeris fitting to infer the relative positions between satellites with high precision. Only the mutual phenomena -- occultations and eclipses -- may achieve better results. However, mutual phenomena only occur every six years in the case of Jupiter. Mutual approximations do not have this restriction and can be observed at any time along the year as long as the satellites are visible. In this work, we present 104 central instants determined from the observations of 66 mutual approximations between the Galilean moons carried out at different sites in Brazil and France during the period 2016--2018. For 28 events we have at least two independent observations. All telescopes were equipped with a narrow-band filter centred at 889 nm with a width of 15 nm to eliminate the scattered light from Jupiter. The telescope apertures ranged between 25--120 cm. For comparison, the precision of the positions obtained with classical CCD astrometry is about 100 mas, for mutual phenomena it can achieve 10 mas or less and the average internal precision obtained with mutual approximations was 11.3 mas. This new kind of simple, yet accurate observations can significantly improve the orbits and ephemeris of Galilean satellites and thus be very useful for the planning of future space missions aiming at the Jovian system.

description: © 2020 The Author(s). Background: Alcohol affects Indigenous communities globally that have been colonised. These effects are physical, psychological, financial and cultural. This systematic review aims to describe the prevalence of current (12-month) alcohol dependence in Indigenous Peoples in Australia, New Zealand, Canada and the United States of America, to identify how it is measured, and if tools have been validated in Indigenous communities. Such information can help inform estimates of likely treatment need. Methods: A systematic search of the literature was completed in six electronic databases for reports on current alcohol dependence (moderate to severe alcohol use disorder) published between 1 January 1989-9 July 2020. The following data were extracted: (1) the Indigenous population studied; country, (2) prevalence of dependence, (3) tools used to screen, assess or diagnose current dependence, (4) tools that have been validated in Indigenous populations to screen, assess or diagnose dependence, and (5) quality of the study, assessed using the Appraisal Tool for Cross-Sectional Studies. Results: A total of 11 studies met eligibility criteria. Eight were cross-sectional surveys, one cohort study, and two were validation studies. Nine studies reported on the prevalence of current (12-month) alcohol dependence, and the range varied widely (3.8-33.3% [all participants], 3-32.8% [males only], 1.3-7.6% [females only]). Eight different tools were used and none were Indigenous-specific. Two tools have been validated in Indigenous (Native American) populations. Conclusion: Few studies report on prevalence of current alcohol dependence in community or household samples of Indigenous populations in these four countries. Prevalence varies according to sampling method and site (for example, specific community versus national). Prior work has generally not used tools validated in Indigenous contexts. Collaborations with local Indigenous people may help in the development of culturally appropriate ways of measuring alcohol dependence, incorporating local customs and values. Tools used need to be validated in Indigenous communities, or Indigenous-specific tools developed, validated and used. Prevalence findings can inform health promotion and treatment needs, including funding for primary health care and specialist treatment services.

description: We study the energy spectrum and the quantized Hall conductance of electrons in a two-dimensional periodic potential with perpendicular magnetic field WITHOUT neglecting the coupling of the Landau bands. Remarkably, even for weak Landau band coupling significant changes in the Hall conductance compared to the one-band approximation of Hofstadter's butterfly are found. The principal deviations are the rearrangement of subbands and unexpected subband contributions to the Hall conductance.

description: Epileptic patients are at risk of experiencing unexpected and random seizures and this lowers their quality of life (QoL) considerably. Automatic seizure onset detectors (SODs) have been proposed to alert the patients before a seizure and in turn improve their QoL. SODs can aid doctors in the diagnosis of epilepsy and detection of seizures which is usually tiring and time consuming; the process requires examining the brain’s electrical activity recorded in an Electroencephalogram (EEG) record. However, the SODs developed in literature are computationally extensive and may not be suitable for clinical adoption. The aim of this thesis is to produce a simple and lightweight SOD that uses characteristics that reflect the neuronal behavior during a seizure. It has been shown that during a seizure, the neurons fire in a synchronized manner and the electrical activity is less chaotic. Hence, two features, the synchronization between EEG channels and the chaoticity of the EEG, have been used to build a patient-specific SOD. Synchronization was measured by the condition number while the recurrence period density entropy estimated the chaoticity of an EEG signal. The extracted features were fed to a support vector machine (SVM) and a neural network classifier for seizure detection. The detectors were validated using a scalp EEG dataset and the SVM-based SOD was able to detect the considered seizures with a sensitivity of 100% and a false positives rate of 0.5 per hour. The results indicate that synchronization and chaos attributes can effectively be used for seizure detection. This work emphasizes the importance of investigating characteristics that are reflective of seizures before building an SOD.

description: This paper is devoted to the study of interactions between stationary electromagnetic sources for the minimal and nonminimal CPT-odd photon sector of the Standard Model Extension (SME), where we search mainly for physical phenomena not present in the Maxwell electrodynamics. First we consider the minimal CPT-odd sector, where the Lorentz violation is caused by the Carroll-Field-Jackiw (CFJ) term, namely $\simε^{μναβ}\left(k_{AF}\right)_μA_νF_{αβ}$, and we treat the Lorentz breaking parameter $\left(k_{AF}\right)^μ$ perturbatively up to second order. We consider effects due to the presence of point-like charges, Dirac strings and point-like dipoles. In special, we calculate the electromagnetic field produced outside the string and investigate the so called Aharonov-Bohm bound states in Lorentz violation context. After, we consider a model where the Lorentz violation is generated by the higher-derivative version of the CFJ model, namely $\simε^{μναβ}V_μA_ν\Box F_{αβ}$, which is a dimension five term of the CPT-odd sector of the nonminimal SME. For this higher-derivative model, we obtain effects up to second order in $V^μ$ related to the presence of point-like charges and a steady current line. We use overestimated constrains for the Lorentz violation parameters in order to investigate the physical relevance of some results found in atomic systems. We also make an overestimate for the background vectors using experimental data from the atomic electric field.

description: We study the exact classical solutions for a real scalar field inside a cavity with a wall whose motion is self-consistently determined by the pressure of the field itself. We find that, regardless of the system parameters, the long-time solution always becomes nonadiabatic and the field's energy concentrates into narrow peaks, which we explain by means of a simple mechanical system. We point out implications for the quantized theory.

Time Based Distributed Energy Resources (DER) Hosting Capacity Analysis (HCA)

description: The world’s electricity demand has been increasing at a rapid pace. Due to the falling prices of Distributed Energy Resources (DERs) and the shift in focus from fossil fuels to renewable sources of many countries from fossil fuels to renewable sources, the integration of DERs is expected to see a rise in the future. This can lead to a wide range of power quality problems in the power system, such as voltage violations, overloading of distribution lines and transformers and reverse power flow. Therefore, it is important to study the effects of the integration of DER on the distribution network to mitigate these negative impacts. In this study, two algorithms have been developed based on the modified iterative method and the Particle Swarm Optimization (PSO) method for Hosting Capacity (HC) determination of a single large-scale DER and multiple DERs. These algorithms calculate the optimal HC based on six scenarios of load and DER generation profiles. The developed algorithms have been tested on the IEEE 123 bus network and their results have been compared. It has been found that the modified iterative method outperforms the PSO method for the single large-scale DER case while only the PSO method can be utilized for the multiple DERs case. It has been concluded that the selection of the HC calculation method should be done carefully and in accordance with the application because each method has its strengths and weaknesses. Software programs that only provide the iterative method cannot be used to calculate the maximum HC of the distribution network for multiple DERs integration. Similarly, programs that only employ stochastic methods are inefficient in finding the optimal size and location for a single large-scale DER. The best performance is achieved when multiple HC methods are used in tandem and the weaknesses of one method are rectified by the strengths of the other.
