Analisis Kinerja Reksadana Saham Dan Reksadana Indeks Dalam Penilaian Tingkat Efisiensi Pasar Modal Indonesia

The objectives of this research are: first, to know whether LQ-45 Index Fund performs better than the equity mutual fund in Indonesian capital market; second, to measure the level of Indonesian capital efficiency. Results show that the raw performance and risk-adjusted performance of the LQ-45 Index Fund is better than the performance of all equity mutual funds (concurrently). For the investors who wish to invest their capital in equity mutual fund, however, we have found two individual equity mutual fund which perform better than the LQ-45 Index Fund, that is Phinisi Dana Saham and Rencana Cerdas. The result of this research also shows that the excess performance of the LQ-45 Index Fund is smaller than the excess performance of (individual) equity mutual fund. From this result, we may conclude that Indonesian capital market is an inefficient capital market

Organizational performance in BAPAREKRAF Indonesia

This study aims to analyze the factors that influence the organizational performance of BAPAREKRAF (The Ministry of Tourism and Creative Economic). BAPAREKRAF is the spearhead of a government agency for developing Indonesia's creative economy. This study's respondents are whole civil servants and civil servant candidates in BAPAREKRAF, in 194 respondents. This research shows that transformational leadership, organizational culture, managerial competence, organizational structure, and organizational trust affect organizational performance, but transactional leadership does not affect organizational performance. Besides that, transformational leadership, organizational culture, organizational structure affect organizational trust, but transactional leadership and managerial competence do not affect organizational trust. Furthermore, transformational leadership, transactional leadership, organizational culture, and organizational structure can be mediated by the trust in organizational performance. However, managerial cannot be mediated by trust in BAPAREKRAF's performance in realizing

primary cutaneous cd30 anaplastic large cell lymphoma in a heart transplant patient case report and literature review

Solid organ transplant recipients are at risk of develop ing a wide range of viral-associated malignancies, in cluding skin tumours and lymphoproliferative disorders. The risk of a post-transplant lymphoproliferative disorder is 28–49 times the risk of a lymphoproliferative disorder in the normal population. Most cases are of B-cell phenotype and are associated with Epstein-Barr virus infection. Post-transplant lymphoproliferative disorders presenting clinically in the skin are rare and usually of B-cell phenotype. Only rare cases of cutaneous T-cell post-transplant lymphoproliferative disorder have been reported previously, mostly mycosis fungoides type. We describe here a rare primary cutaneous T-cell lymphoma CD30+ arising in a heart transplant patient who had a nodule on the right leg, several years after heart transplantation. The morphology and immunohistochemical findings were consistent with a CD30+ anaplastic large cell lymphoma with a T-cell phenotype. Excisional biopsy and radiotherapy of the affected area were performed. In this patient, the presence of a solitary lesion and th

Modeling and performance assessment of the split-pi used as a storage converter in all the possible dc microgrid scenarios. Part i: Theoretical analysis

The integration of an electrical storage system (ESS) into a DC microgrid using a bidirectional DC/DC converter provides substantial benefits but requires careful design. Among such converter topologies, the Split-pi converter presents several merits at the cost of non-isolated operation. However, the few works in the literature on the Split-pi presented only closed-loop control with a single control loop; furthermore, they neglected the reactive components’ parasitic resistances and did not perform any experimental validation. This work aimed at investigating the use of the Split-pi converter as a power interface between an ESS and a DC microgrid. Five typical microgrid scenarios are presented, where each of which requires a specific state-space model and a suitable control scheme for the converter to obtain high performance. In this study, two different state-space models of the converter that consider the parasitic elements are presented, the control schemes are discussed, and criteria for designing the controllers are also given. Several simulations, as well as experimental tests on a prototype realized in the lab, were performed to validate the study. Both the simulation and experimental results will be presented in part II of this work. The proposed approach has general validity and can also be followed when other bidirectional DC/DC converter topologies are employed to interface an ESS with a DC microgrid

Modeling and Experimental Validation of a Voltage-Controlled Split-Pi Converter Interfacing a High-Voltage ESS with a DC Microgrid

The Split-pi converter can suitably interface an energy storage system (ESS) with a DC microgrid when galvanic isolation is not needed. Usually, the ESS voltage is lower than the grid-side voltage. However, limitations in terms of the ESS current make the use of a high-voltage ESS unavoidable when high power levels are required. In such cases, the ESS voltage can be higher than the microgrid voltage, especially with low microgrid voltages such as 48 V. Despite its bidirectionality and symmetry, the Split-pi exhibits a completely different dynamic behavior if its input and output ports are exchanged. Thus, the present work aims to model the Split-pi converter operating with an ESS voltage higher than the grid-side voltage in three typical microgrid scenarios where the controlled variable is the converter's output voltage. The devised state-space model considers the parasitic elements and the correct load model for each scenario. Furthermore, it is shown that the presence of the input LC filter can make the design of the loop controllers more complicated than in the case of a lower ESS voltage than the grid-side voltage. Finally, the study is validated through simulations and experimental tests on a lab prototype, and a robustness analysis is performed

Modeling and performance assessment of the split-pi used as a storage converter in all the possible dc microgrid scenarios. Part II: Simulation and experimental results

Bidirectional DC/DC converters such as the Split-pi can be used to integrate an energy storage system (ESS) into a DC microgrid providing manifold benefits. However, this integration deserves careful design because the ESS converter must behave like a stiff voltage generator, a non-stiff voltage generator, or a current generator depending on the microgrid configuration. Part I of this work presented a comprehensive theoretical analysis of the Split-pi used as an ESS converter in all the possible DC microgrid scenarios. Five typical microgrid scenarios were identified. Each of them required a specific state-space model of the Split-pi and a suitable control scheme. The present paper completes the study validating the theoretical analysis based on simulations and experimental tests. The chosen case study encompassed a 48 V, 750 W storage system interfaced with a 180 V DC microgrid using a Split-pi converter. It can represent a reduced-power prototype of terrestrial and marine microgrids. A prototypal Split-pi converter was realized in the lab, and several experimental tests were performed to assess the performance in each scenario. The results obtained from the experimental tests were coherent with the simulations and validated the study

Dye lasing in optically manipulated liquid aerosols

We report lasing in airborne, rhodamine B-doped glycerol-water droplets with diameters ranging between 7.7 and 11.0 mu m, which were localized using optical tweezers. While being trapped near the focal point of an infrared laser, the droplets were pumped with a Q-switched green laser. Our experiments revealed nonlinear dependence of the intensity of the droplet whispering gallery modes (WGMs) on the pump laser fluence, indicating dye lasing. The average wavelength of the lasing WGMs could be tuned between 600 and 630 nm by changing the droplet size. These results may lead to new ways of probing airborne particles, exploiting the high sensitivity of stimulated emission to small perturbations in the droplet laser cavity and the gain medium

L'EIC e\u300 caratterizzata dalla presenza di lesioni parenchimali irreversibili, risultato di una lunga esposizione a regimi pressori patologici specie in pazienti che non seguono o non rispondono alle comuni terapie mediche. Si riscontrano quali reperti tipici multipli esiti gliotici, leucoaraiosi e multiple lesioni lacunari con predilezione per le localizzazioni profonde ai nuclei lenticolari, ai talami e al ponte. Piu\u300 raramente possono evidenziarsi minuti foci emorragici parenchimali, piu\u300 frequentemente localizzati nei gangli della base ma anche nel ponte e nel cervelletto, che in alcuni casi possono rappresentare la manifestazione principale della patologia: questi microsanguinamenti, visibili incostantemente in TC, sono classicamente ben individuabili in RM come aree di netta ipointensita\u300 di segnale in GRE (Gradient Recalled Echo) T2* pesate. Scopo del nostro lavoro e\u300 quello di presentare due casi in cui l'EIC si manifesta prevalentemente con un quadro micro-emorragico confrontando la sensibilita\u300 delle convenzionali sequenze GRE T2* pesate con sequenze sensibili al fenomeno della suscettivita\u300 magnetica (Susceptibility-Weighted Imaging, SWI) di piu\u300 recente introduzione nella routine diagnostica
