Subgradient methods for convex minimization
No full textThesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2002.Includes bibliographical references (p. 169-174).This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Many optimization problems arising in various applications require minimization of an objective cost function that is convex but not differentiable. Such a minimization arises, for example, in model construction, system identification, neural networks, pattern classification, and various assignment, scheduling, and allocation problems. To solve convex but not differentiable problems, we have to employ special methods that can work in the absence of differentiability, while taking the advantage of convexity and possibly other special structures that our minimization problem may possess. In this thesis, we propose and analyze some new methods that can solve convex (not necessarily differentiable) problems. In particular, we consider two classes of methods: incremental and variable metric.by Angelia NediÄ.Ph.D

No full textThis Final Project Report was prepared by Angelia Rachel Aiena, Student
Identification Number 2041211011, with the title “IMPOSITION OF LOCAL
TAX OBLIGATIONS AND INCOME TAX 23 ON CATERING SERVICES AT
RSUD R. SYAMSUDIN S.H.” This report is prepared based on the results of
research conducted by the author at RSUD R. Syamsudin S.H. Prior to the issuance
of Law No. 28/2009, catering services were included in the Value Added Tax object.
After the issuance of the Act, catering services have been excluded from the object
of Value Added Tax and are subject to the object of Regional Tax in accordance
with the provisions of Law No. 1 of 2022 concerning Financial Relations between
the Central Government and Regional Governments and are subject to Income Tax
23 in accordance with the provisions of PMK No. 141/PMK.03/2015 concerning
Other types of services as referred to in Article 23 Paragraph (1) Letter C Number
2 of Law Number 7 of 1983 concerning Income Tax. The purpose of this research
is to find out how tax imposition, tax calculation and constraints on eating and
drinking in hospitals. The research method used in this research is a qualitative
research method with a descriptive method so that the results of this research are
based on direct observation through sources with interview, observation, and
documentation methods to find out how the imposition of local taxes and income
tax 23 on catering services at RSUD. R Syamsudin S.H and its constraints and
solutions. As PMK No. 141/PMK.03/2015 explains that Catering Services are
subject to an Income Tax 23 rate of 2% of the gross amount and are subject to local
tax rates as referred to in Law No. 1 of 2022 of 10% of the Tax Imposition Base
(DPP). The results of research at RSUD R. Syamsudin S.H in the imposition of local
tax obligations and Income Tax 23 on catering services are in accordance with
these regulations
The relationship between attributional style and depression, 1991
No full textThe purpose of this research was to determine whether a relationship existed between an individual's attributional style and the presence of depression. Attributions! style was measured across three dimensions: (1) internal verses external causality, (2) stable verses temporary causality, and (3) global verses domain specific causality. In addition to the Attributional Style Questionnaire, the Beck Depression Inventory and the Generalized Contentment Scale were given to 65 participants, 30 depressed and 35 nondepressed. This research found support for depressed individual's possessing a different attributional style from nondepressed subjects when they perceived themselves to have no control over the stressful life events

Under flooded paddy conditions, arsenic becomes plant-available as iron-reducing conditions ensue, while oxic conditions lead to increased plant availability of Cd in acidic soils. Because Cd enters rice through Mn transporters, we hypothesized that irrigation resulting in intermediate redox could simultaneously limit both As and Cd in rice grain due to As retention in soil and Mn competition for Cd uptake. In a 2 year field study, we used 6 irrigation managements that varied in extent and frequency of inundation, and we observed strong effects of irrigation management on porewater chemistry, soil redox potentials, plant As and Cd concentrations, plant nutrient concentrations, and methane emissions. Plant As decreased with drier irrigation management, but in the grain this effect was stronger for organic As than for inorganic As. Grain organic As, but not inorganic As, was strongly and positively correlated with cumulative methane emissions. Conversely, plant Cd increased under more aerobic irrigation management and grain Cd was negatively correlated with porewater Mn. A hazard index approach showed that in the tested soil with low levels of As and Cd (5.4 and 0.072 mg/kg, respectively), irrigation management could not simultaneously decrease grain As and Cd. Many soil properties, such as reducible As, available Cd, soil pH, available S, and soil organic matter should be considered when attempting to optimize irrigation management when the goal is decreasing the risk of As and Cd in rice grain.This work was funded by the National Science Foundation (grant #1930806)
Perancangan Media Informasi Berupa E-book mengenai Sustainable Living melalui Eco Enzyme
No full textPopulasi manusia kian bertambah sedangkan kualitas dan kuantitas sumber daya alam memiliki ambang batas. Timbunan sampah organik yang setiap hari manusia hasilkan terbuang ke alam dengan sia-sia dan justru ikut menyumbang kerusakan lingkungan. Padahal apabila sampah organik tersebut dipilah dan diolah menjadi eco enzyme, sampah organik justru mampu memberi beragam manfaat untuk berbagai pihak termasuk ibu rumah tangga. Manfaat yang paling dirasakan melalui eco enzyme yaitu ibu rumah tangga dapat menghemat pengeluaran untuk membeli berbagai produk kebersihan rumah tangga seperti sabun cuci piring, deterjen, obat pel hingga sabun dan shampoo kebutuhan mandi. Dengan demikian selain berguna untuk meminimalisir penggunaan sumber daya alam baru, eco enzyme juga mampu mengurangi penggunaan bahan kimia yang sesungguhnya tidak ramah untuk lingkungan dan bertentangan dengan prinsip sustainable living. Kondisi tersebut mendorong penulis untuk memperkenalkan eco enzyme secara lebih luas kepada ibu rumah tangga di kawasan Tangerang sebagai sarana sustainable living. Oleh sebab itu penulis memilih media informasi sebagai teknik yang paling tepat untuk menyampaikan informasi kepada target sasaran secara lebih lengkap. Informasi dapat disampaikan melalui media cetak seperti buku atau koran dan dapat pula melalui media digital seperti media sosial dan website. Agar penyampaian informasi menjadi efektif, pemilihan media informasi utama dan media informasi pendukung tentu akan disesuaikan dengan kemampuan dan potensi target sasaran dalam menjangkau media tersebut
Building Social Resilience Through Parks and Common Recreational Spaces
No full textThere is an increasing body of research that validates the connection between the quality of the physical environment and human health. In particular, the provision of public parks that are easily accessible to city dwellers is considered highly valuable. Green open spaces, in addition to their environmental benefits, have the potential to increase people’s physical activity levels. With apt designs, parks offer a multi-sensorial environment that stimulates and improves mental health. These multi-tasking spaces also bring about social benefits; they provide opportunities for users of urban parks to interact with other users, and for users to become attached to the area (place attachment). Social interaction and place attachment are thought to contribute toward social cohesion, a collective identity and community support. These are all characteristics of resilient cities. Singapore’s National Parks Board has undertaken a series of research studies in collaboration with medical professionals, that seek to understand these important aspects of social resilience in cities.</p
