Neupane K, Gautam AP, Regmi A. 2017. Trends of land cover change in a key biological corridor in Central Nepal. Asian J For 1: 50-55. The study analyzed the changes in land cover in one of the key biological corridors in Central Nepal called the Barandabhar Corridor located in Chitwan District, during the last two decades (i.e. 1991 to 2013). The study is based on analysis of satellite imageries (Landsat 5 TM of 1991 and Landsat 8 OLI_TIRS of 2013) and primary data on drivers of land cover change, collected from the field. Supervised Maximum Likelihood method of image classification was used to produce the land cover maps for 1991 and 2013. The result showed that forest cover in the corridor increased by 7.03% while the coverage of shrubland, water and other land cover types decreased during the study period. Implementation of community based forest management programs, low dependency on forest resources, and increase in conservation awareness among the local people are found to be the main causes behind the increase in forest cover.

AbstractEvaluating the accuracy of precipitation products is essential for many applications. The traditional method for evaluation is to calculate error metrics of products with gauge measurements that are considered as ground-truth. The multiplicative triple collocation (MTC) method has been demonstrated powerful in error quantification of precipitation products when ground-truth is not known. This study applied MTC to evaluate five precipitation products in Germany: two raw satellite-based (CMORPH and PERSIANN), one reanalysis (ERA-Interim), one soil moisture-based (SM2RAIN-ASCAT), and one gauge-based (REGNIE) products. Evaluation was performed at the 0.5° -daily spatial-temporal scales. MTC involves a log transformation of data, necessitating dealing with zero values in daily precipitation. Effects of 12 different strategies for dealing with zero value on MTC results were investigated. Seven different triplet combinations were tested to evaluate the stability of MTC. Results showed that different strategies for replacing zero values had considerable effects on MTC-derived error metrics particularly for root mean squared error (RMSE). MTC with different triplet combinations generated different error metrics for individual products. MTC-derived correlation coefficient (CC) was more reliable than RMSE. It is more appropriate to use MTC to compare the relative accuracy of different precipitation products. Based on CC with unknown truth, MTC with different triplet combinations produced the same ranking of products as the traditional method. A comparison of results from MTC and the classic TC with additive error model showed the potential limitation of MTC in arid area or dry time periods with large ratio of zero daily precipitation.

As a continuation from the first and second Maritime Sciences and Advanced Technology (MSAT) conference on August 3-5, 2017, in Denpasar, Bali, and on August 7-8, 2019 in Makassar, we heartfully worked on the 3rd MSAT Conference “Toward Ocean Sustainability for a Better Future Through Sciences and Technology” initially taken place at Pangandaran Integrated Aquarium and Marine Research Institute (PIAMARI), Pangandaran, West Java, 5-6th August 2021 (https://msat.fitb.itb.ac.id/). This conference is one of our Memorandum of Agreement the implementations between the Faculty of Earth Science and Technology - ITB, Geospatial Information Agency of Indonesia, and the PIAMARI, Maritime Affairs and Fisheries. Topic, as mentioned above, is chosen to support Sustainable Development Goals (SDGs) promoted by the United Nations. The Maritime science, and technology targets at least the SDGs no 13 and 14; Climate Action and Life below water. While several others like no.1 (No Poverty) and 2 (Zero Hunger) and no. 7 (Affordable and clean energy) are also strongly workable from the Maritime section, especially our country as we are the second-largest coastline in the world. This makes 60% of our citizens live in the coastal area. Moreover, our earth system is highly likely sensitive to climate change and might continuously affect the future climate. The global surface temperature will continue to increase until at least the mid-century under all emissions scenarios considered. Global warming of 1.5°C and 2°C will be exceeded during the 21st century unless deep reductions in CO2 and other greenhouse gas emissions occur in the coming decades. Our first Conference proceeding (Volume 62) was published at IOP on 06 July 2018 (https://iopscience.iop.org/issue/1755-1315/162/1), and our second conference proceeding (Volume 618) was published at IOP on 21 December 2020 (https://iopscience.iop.org/issue/1755-1315/6187/1). The proceeding covers the important impact of the geographical position of the Indonesian Seas. We have welcomed various research findings from the aspects of Ocean-Atmosphere Dynamics, Marine Hazard and Coastal Degradation, Marine Resources, Conservation and ICZM, and Marine Geodesy and Satellite Oceanography – as have become the sessions. Therefore, in this Conference Proceeding, readers might discover the recent issue and results of research in the broad topics of maritime science and advanced technology. Unfortunately, the 3rd MSAT must be held online using the Zoom platform due to Covid-19. On June-September 2021, Indonesia was experiencing the high-risk status of Covid-19, which was under activity restrictions. We chose to keep the dates fixed on August 5-6, 2021, although we have to hold the conference virtually instead of postponing it on other dates. The reason is to keep all the speakers on schedule, and administration supports are in place. Additionally, world oceans day, commemorated on June 8, was framed for celebration. By the advantages, participants from many remote areas in Indonesia joined this virtual conference. The organizers were in 3 different cities of Bandung (ITB), Jakarta (BIG), and Pangandaran (PIAMARI). In Bandung, the MSAT committee was assigned to the faculty within several different rooms to comply with the health protocol during the pandemic. The participants who attended online on the first and second day were about 250 participants from various institutions and universities in Indonesia and teachers in Pangandaran, 3 keynote speakers and 9 invited speakers, and 53 presenters. The invited speakers were well-known scientists around the world (USA, China, Japan, Korea, Australia, and New Zealand), hence attracted some participant from abroad. The opening was opened by the Dean of the Faculty of Earth Science and Technology, Dr. Irwan Meilano, S.T., M.Sc., and ITB Chancellor, Prof. Reini Wirahadikusumah. After that, it was continued with the Keynote Speaker of the Minister of Maritime Affairs and Fisheries of Indonesia, Mr. Ir. Sakti Wahyu Trenggono, M.M., and continued with a mini session which was opened with a breakout room system (Room A, B, C, D, and E) on Zoom. Keynote Speakers were given 30 minutes to present the talk, and Invited speakers were allocated for 20 minutes talk and 10 minutes Q&A session guided by the assigned moderator. Meanwhile, every participant presents their works maximum of 15 minutes, followed by 5 minutes of Q&A session guided by the moderator for each morning and afternoon session. The event starts on time from 08.00 to 17.00. The MSAT event can also be watched through the Oceanography Study Program Youtube: Oceanography ITB (https://www.youtube.com/channel/UCtLdITrN051L6wpa5KtwG7A) List of the organizing committee is listed as follows, Photo documentation are available in this pdf.

L’esercito italiano e la conquista della Catalogna (1808-1811) Uno studio di Military Effectiveness nell’Europa napoleonica Settori scientifico-disciplinari SPS/03 – M-STO/02 La ricerca ha lo scopo di ricostruire e valutare l’effettività militare dell’esercito italiano al servizio di Napoleone I. In primo luogo attraverso un’analisi statistica e strategica della costruzione, e del successivo impiego, dell’istituzione militare del Regno d’Italia durante gli anni della sua esistenza (1805-14); successivamente, è stato scelto un caso di studi particolarmente significativo, come la campagna di Catalogna (1808-11, nel contesto della guerra di Indipendenza spagnola), per poter valutare il contributo operazionale e tattico dei corpi inviati dal governo di Milano e la loro integrazione con l’apparato militare complessivo del Primo Impero. La tesi ha voluto rispondere alla mancanza di studi sul comportamento in guerra dell’esercito italiano e, allo stesso tempo, introdurre nella storiografia militare italiana la metodologia di studi, d’origine anglosassone e ormai di tradizione trentennale, di Military Effectiveness. La ricerca si è primariamente basata, oltre che sulla copiosa memorialistica a stampa italiana e francese, sulla documentazione d’archivio della Secrétairerie d’état impériale (Archives Nationales di Pierrefitte-sur-Seine, Parigi), del Ministère de la Guerre francese (Service historique de la Défence, di Vincennes, Parigi) e del Ministero della Guerra del Regno d’Italia (Archivio di Stato di Milano). Dal punto di vista dei risultati è stato possibile verificare come l’esercito italiano abbia rappresentato, per Bonaparte, uno strumento duttile e di facile impiego, pur in un contesto di sostanziale marginalità numerica complessiva di fronte alle altre (e cospicue) forze messe in campo da parte dell’Impero e dei suoi altri Stati satellite e alleati. Per quanto riguarda la campagna di conquista della Catalogna è stato invece possibile appurare il fondamentale contributo dato dal contingente italiano, sotto i punti di vista operazionale e tattico, per la buona riuscita dell’invasione; questo primariamente grazie alle elevate caratteristiche generali mostrate dallo stesso, ma anche per peculiarità disciplinari e organizzative che resero i corpi italiani adatti a operazioni particolarmente aggressive.
The Italian Army and the Conquest of Catalonia (1808-1811) A Study of Military Effectiveness in Napoleonic Europe Academic Fields and Disciplines SPS/03 – M-STO/02 The research has the purpose of reconstruct and evaluate the military effectiveness of the Italian Army existed under the reign of Napoleon I. Firstly through a statistic and strategic analysis of the development, and the following deployment, of the military institution of the Kingdom of Italy in the years of its existence (1805-14). Afterwards, a particularly significant case study was chosen, as the campaign of Catalonia (1808-11, in the context of the Peninsular War), in order to assess the operational and tactical contribution of the regiments sent by the Government of Milan and their integration in the overall military apparatus of the First Empire. The thesis wanted to respond to the lack of studies on the Italian army’s behavior in war and, at the same time, to introduce the methodology of the Military Effectiveness Studies (of British and American origin and, by now, enriched by a thirty-year old tradition) in the Italian historiography. The research is primarily based, besides the numerous memoirs of the Italian and French veterans, on the archive documentation of the Secrétairerie d’état impériale (Archives Nationales of Pierrefitte-sur-Seine, Paris), of the French Ministère de la Guerre (Service historique de la Défence, of Vincennes, Paris) and of the Italian Ministero della Guerra (Archivio di Stato di Milano). About the results, it has been verified how the Italian army has become a flexible and suitable instrument for Bonaparte, albeit in a context of substantial overall numerical marginality in comparison to the heterogeneous forces available to the Empire and its others satellites and allied states. Regarding the campaign of Catalonia, instead, it was possible to ascertain the fundamental contribution of the Italian regiments, in an operational and tactical perspective, for the success of the invasion. This was primarily due to the excellent general characteristics shown by the expeditionary force, but also to disciplinary and organizational peculiarities that have made the Italian corps suitable for particularly aggressive operations.

High-power planar waveguide lasers that emit in a single mode are of interest for applications in such diverse fields as satellite communications, nonlinear optics or optical computing, for example, an output power of an emitting semiconductor laser may be increased by broadening the stripe width of the active region. However, this generally causes multimode operation in the laser. Furthermore surface emitting lasers provide a broad emission regin to generate large amounts of optical power, but large surface area emitters also produce multimode emission.
