Spatio Temporal Unity Networking for Video Anomaly Detection
Venue: IEEE Access
Year: 2019

Anomaly detection in video surveillance is challenging due to the variety of anomaly types and definitions, which limit the use of supervised techniques. As such, auto encoder structures, a type of classical unsupervised method, have recently been utilized in this field. These structures consist of an encoder followed by a decoder and are typically adopted to restructure a current input frame or predict a future frame. However, regardless of whether a 2D or 3D autoencoder structure is adopted, only single scale information from the previous layer is typically used in the decoding process. This can result in a loss of detail that could potentially be used to predict or reconstruct video frames. As such, this study proposes a novel spatio temporal U Net for frame prediction using normal events and abnormality detection using prediction error. This framework combines the benefits of U Nets in representing spatial information with the capabilities of ConvLSTM for modeling temporal motion data. In addition, we propose a new regular score function, consisting of a prediction error for not only the current frame but also future frames, to further improve the accuracy of anomaly detection. Extensive experiments on common anomaly datasets, including UCSD (98 video clips in total) and CUHK Avenue (30 video clips in total) validated the performance of the proposed technique and we achieved 96.5% AUC for the Ped2 dataset, which is much better than existing autoencoder based and U Net based methods.
Old growth forests as global carbon sinks
Venue: Nature
Year: 2008

Old growth forests remove carbon dioxide from the atmosphere at rates that vary with climate and nitrogen deposition. The sequestered carbon dioxide is stored in live woody tissues and slowly decomposing organic matter in litter and soil. Old growth forests therefore serve as a global carbon dioxide sink, but they are not protected by international treaties, because it is generally thought that ageing forests cease to accumulate carbon. Here we report a search of literature and databases for forest carbon flux estimates. We find that in forests between 15 and 800 years of age, net ecosystem productivity (the net carbon balance of the forest including soils) is usually positive. Our results demonstrate that old growth forests can continue to accumulate carbon, contrary to the long standing view that they are carbon neutral. Over 30 per cent of the global forest area is unmanaged primary forest, and this area contains the remaining old growth forests. Half of the primary forests (6 x 108 hectares) are located in the boreal and temperate regions of the Northern Hemisphere. On the basis of our analysis, these forests alone sequester about 1.3 0.5 gigatonnes of carbon per year. Thus, our findings suggest that 15 per cent of the global forest area, which is currently not considered when offsetting increasing atmospheric carbon dioxide concentrations, provides at least 10 per cent of the global net ecosystem productivity. Old growth forests accumulate carbon for centuries and contain large quantities of it. We expect, however, that much of this carbon, even soil carbon, will move back to the atmosphere if these forests are disturbed.

Although the Indonesian Broadcasting Commission (KPI) supervised all of the television programs, there are a lot of programs getting a warning because of breaking the rule of P Broadcasting Code of Conduct (P3) and Broadcasting Program Standard (SPS) Focusing on the program Pagi Pagi Pasti Happy, this research investigated the authority of KPI in terms of being a watchdog of television content in Indonesia. This research deployed political economy theory because it has studied not only media analysis in general but also the problems faced by the media industry and who controlled media. To criticize the authority of KPI in maintaining a code of conduct over the broadcasting content, three KPI's commissioners, two television program representatives, and a media observer were interviewed. Based on interviews, the researcher found that dialogue preferred by KPI in supervising the television content confirmed that the current KPI's commissioner has compromised with private television stations. KPI is more likely to support the existing television business system nowadays to gain maximum profit for the media investor. The findings suggest that role of KPI's commissioner has been used to gain more power in the future.

Hybrid deep neural networks for recommender systems
Venue: Neurocomputing
Year: 2020

More recently, deep neural networks received much attention from the recommender systems community where CNNs and RNNs were applied in different recommendation contexts and achieved state of the art results on many publicly available benchmarks. While the success of the neural models came from their high expressiveness, the uninterpretability problem still one of their main drawbacks, which can have a negative side effect on the whole learning process. A good candidate to reduce the uninterpretability is using Probabilistic Soft Logic (PSL) which showed a strong performance in dealing with this problem. Moreover, sparsity is another major problem of the most previous recommendation systems. In this paper, we introduce a new recommender system framework based on the generalized distillation principle that combines two modeling approaches: PSL for the knowledge driven modeling approach and deep neural networks for the data driven approach. Experimental results on publicly available datasets show that our method significantly outperforms the previous state of the art based on deep neural networks emphasizing the utility of PSL rules in handling inconsistencies, reducing the uninterpretability of the neural models and shows promising results in dealing with sparsity.
Exploring Notice and Choice: Design Guidelines for a User Centered Permission Model for Personalized Services
Year: 2013

When users install an application on their mobile Android device, they must decide whether to grant the application access to privacy sensitive information. Building upon recent research on the limitations of the current installation dialog, we investigate a new permission model better aligned with users' current understanding of data collection and privacy concerns. Using three mobile applications that offer highly personalized services, we conduct a series of online surveys (n 1,316) varying the information disclosed in the installation screen and exploring the option to limit data collection. First, we identify two factors that significantly affect users' willingness to install applications the frequency of data collection and the third party sharing policy and find that in the absence of such information, as in the case of existing dialogs, many survey respondents incorrectly assume that an application's capabilities are more restricted than they actually are. Second, we find that offering a third option beyond existing all or nothing choice affects users' willingness to install applications. We further analyze how our participants would like to limit data collection, and compile a set of suggestions for the design of a permission model that can provide better privacy notice and meaningful controls to users.
Quality of life of female and male vegetarian and vegan endurance runners compared to omnivores results from the NURMI study (step 2)
Venue: Journal of the International Society of Sports Nutrition
Year: 2018

BackgroundHealth related effects of a vegetarian or vegan diet are known to support parameters positively affecting exercise performance in athletes, whereas knowledge about psyche and wellbeing is sparse. Therefore, the aim of the Nutrition and Running High Mileage (NURMI) Study (Step 2) was to compare Quality of Life (QOL) scores among endurance runners following a vegetarian or vegan diet against those who adhere to an omnivorous diet.MethodsThe study was conducted following a cross sectional design. A total of 281 recreational runners (159 women, 122 men) completed the WHOQOL BREF questionnaire consisting of the domains physical health, psychological wellbeing, social relationships and environment, which generates scores on a scale from 4 to 20. Data analysis was performed using ANOVA.ResultsIt was found that 123 subjects followed an omnivorous diet and 158 adhered to a vegetarian/vegan diet. There were 173 runners who met the inclusion criteria 'NURMI Runners' among them 103 half marathoners and 70 marathoners and ultramarathoners, as well as 108 10 km runners as control group. Overall QOL scores were high 16.62 1.91) Men had higher scores than women due to high scores in the physical health and psychological well being dimensions. Adhering to an omnivorous diet affected environment scores for women and social relationships scores for men. A minor effect concerning race distance was observed in women, where half marathoners had a higher environmental score than 10 km runners. A moderate dietxrace distance interaction on environment scores was shown for men.ConclusionsThe results revealed that endurance runners had a high QOL regardless of the race distance or diet choice. These findings support the notion that adhering to a vegetarian or vegan diet can be an appropriate and equal alternative to an omnivorous diet.
Feeding Management of Backyard Goats in Northern Mindanao Philippines
Year: 2019

A survey was conducted to assess the feeding management of goats among backyard raisers in Northern Mindanao, Philippines. There were 34 backyard goat raisers included in the survey taking into account the production systems employed, the kind of feed materials provided/are available for their goats and the usual supplementation practices. From the 34 farmers, 13 or 38.23% practiced rapid rotational tethering (RRT) while 10 (29.41% maintained free grazing (FG) Accordingly, some realized the need and the benefit to shift to partial (17.65% and complete confinement (5.82% The shift is due mainly to the limitedgrazing area and the better growth performance when animals are confined. However, backyard goats in the region (Northern Mindanao)are still characterized by the low dam and kid performance with high pre weaning mortalities. Supplementation is practiced whenever supplemental feed is available. The abundance of forages is noted during the wet season but the sustainability of supply during dry season remains a problem. Nutrient deficiency is perceived throughout the year due to low digestibility of forages even during the rainy season and to the limited forage during the dry season. The condition will worsen if dry spell extends into drought.
Bayesian Optimization Algorithm with Agent based Supply Chain Simulator for Multi echelon Inventory Management
Venue: 2020 IEEE 16th International Conference on Automation Science and Engineering (CASE)
Year: 2020

Supply chain inventory optimization is essential to ensure supply chain efficiency and to increase customer satisfaction. However, it is challenging because of the inherent uncertainties and complex dynamics in real world supply chains. Researchers and practitioners have turned to simulation based optimization methods to solve analytically intractable multi echelon inventory optimization problems. Whereas, simulation based optimization methods are usually computationally expensive. An efficient optimization procedure will greatly enhance the applicability of these methods. In this paper, we propose a Bayesian optimization approach along with an agent based supply chain simulator to solve a constrained multi echelon inventory optimization problem that requires fewer number of interactions with the simulator. Our proposed approach is compared with the most popularly used algorithm, genetic algorithm (GA) The experimental results demonstrate that the proposed method converges to the optimal solution significantly faster than GA.
Diasporic audiences and non resident media: The case of Indian films
Year: 2011

This article seeks to demonstrate how various overlapping claims made by politicians, film producers and academics regarding diasporic audiences have constructed a particular model of cultural transmission emerging from a globalised mediasphere. Taking the case of popular Indian films and their global circulation, this article goes on to challenge the dominant ethnocultural explanations of popular culture and its circulation. Following a consideration of the empirical and epistemological faultlines arising from that paradigm, it is claimed that the tidy equation of media dispersal with migrant ethnicities is not only problematic in this specific case, but also that it provides for misleading conclusions about the relationship between cultural identity and media consumption. On reflection, it is argued that the epistemological foundation of global audience studies must provide for a greater recognition of the subjective and demographic diversity of audiences as well as the inherent hybridity and multiplication of media sources in everyday experience.
Immune Checkpoint Blockade in Cancer Therapy.
Venue: Journal of clinical oncology official journal of the American Society of Clinical Oncology
Year: 2015

Immunologic checkpoint blockade with antibodies that target cytotoxic T lymphocyte associated antigen 4 (CTLA 4) and the programmed cell death protein 1 pathway (PD 1/PD L1) have demonstrated promise in a variety of malignancies. Ipilimumab (CTLA 4) and pembrolizumab (PD 1) are approved by the US Food and Drug Administration for the treatment of advanced melanoma, and additional regulatory approvals are expected across the oncologic spectrum for a variety of other agents that target these pathways. Treatment with both CTLA 4 and PD 1/PD L1 blockade is associated with a unique pattern of adverse events called immune related adverse events, and occasionally, unusual kinetics of tumor response are seen. Combination approaches involving CTLA 4 and PD 1/PD L1 blockade are being investigated to determine whether they enhance the efficacy of either approach alone. Principles learned during the development of CTLA 4 and PD 1/PD L1 approaches will likely be used as new immunologic checkpoint blocking antibodies begin clinical investigation.

Functional Regularisation for Continual Learning using Gaussian Processes
Venue: ICLR
Year: 2020

We introduce a framework for Continual Learning (CL) based on Bayesian inference over the function space rather than the parameters of a deep neural network. This method, referred to as functional regularisation for Continual Learning, avoids forgetting a previous task by constructing and memorising an approximate posterior belief over the underlying task specific function. To achieve this we rely on a Gaussian process obtained by treating the weights of the last layer of a neural network as random and Gaussian distributed. Then, the training algorithm sequentially encounters tasks and constructs posterior beliefs over the task specific functions by using inducing point sparse Gaussian process methods. At each step a new task is first learnt and then a summary is constructed consisting of (i) inducing inputs a fixed size subset of the task inputs selected such that it optimally represents the task and (ii) a posterior distribution over the function values at these inputs. This summary then regularises learning of future tasks, through Kullback Leibler regularisation terms. Our method thus unites approaches focused on (pseudo )rehearsal with those derived from a sequential Bayesian inference perspective in a principled way, leading to strong results on accepted benchmarks.
A ZCS Isolated Full Bridge Boost Converter with Multiple Inputs
Venue: 2007 IEEE Power Electronics Specialists Conference
Year: 2007

A modular based, zero current switched (ZCS) isolated full bridge boost converter with multiple inputs is presented. By connecting a simple auxiliary circuit, between the full bridge input and the input choke, in each module, the transformer leakage inductance and output capacitance of the switching devices are used to create a quasi resonant path for facilitating ZCS of all full bridge switching devices. The operation of the auxiliary circuit integrates into the FB circuit and each auxiliary circuit operates independently among the modules. Thus, the operation of the multiple input structure will not be affected by the newly added auxiliary circuits, but, at the same time, all switches become zero current switched. A 290 W prototype with two input voltages of 5 V and 12 V has been tested and built. Theoretical predictions are verified with the experimental measurement results. The effectiveness of the proposed auxiliary circuit on improving the conversion efficiency is studied.
Lean as an Integrator of Modular Construction
Venue: Modular and Offsite Construction (MOC) Summit Proceedings
Year: 2019

The use of Lean concepts is growing in several industrial sectors. Corporations are seeking new ways to achieve improved operational performance and to identify process improvement measures to improve workflows. The research presented in this proposes to achieve a conceptual framework that can be used in the modular construction market. The research method selected is Design Science Research (DSR) since the research proposes to create a new artifact constituting the integration of Lean Manufacturing, Lean Thinking, Lean Construction and Lean Office in a consistent manner and one that can accommodate Integrated Project Delivery (IPD) In this paper, Permanent Modular Construction (PMC) will be investigated as an industrial construction process. PMC consists of the manufacture of components of the building with volumetric geometry, produced outside the construction site in a factory environment and then transported to the worksite to be assembled with a set of other modules, with comparably few construction activities carried out on site. In order to execute projects using this construction method it is necessary to integrated design, factory operations, transportation and construction site operations, accounting for different locations and different characteristics in a single workflow: this is one of the primary challenges of PMC.
