Input Fast-Forwarding for Better Deep Learning
This paper introduces a new architectural framework, known as input
fast-forwarding, that can enhance the performance of deep networks. The main
idea is to incorporate a parallel path that sends representations of input
values forward to deeper network layers. This scheme is substantially different
from "deep supervision" in which the loss layer is re-introduced to earlier
layers. The parallel path provided by fast-forwarding enhances the training
process in two ways. First, it enables the individual layers to combine
higher-level information (from the standard processing path) with lower-level
information (from the fast-forward path). Second, this new architecture reduces
the problem of vanishing gradients substantially because the fast-forwarding
path provides a shorter route for gradient backpropagation. In order to
evaluate the utility of the proposed technique, a Fast-Forward Network (FFNet),
with 20 convolutional layers along with parallel fast-forward paths, has been
created and tested. The paper presents empirical results that demonstrate
improved learning capacity of FFNet due to fast-forwarding, as compared to
GoogLeNet (with deep supervision) and CaffeNet, which are 4x and 18x larger in
size, respectively. All of the source code and deep learning models described
in this paper will be made available to the entire research communityComment: Accepted in the 14th International Conference on Image Analysis and

Future Community-Based Ecotourism (CBET) development
Ecotourism is an alternative form of tourism and is usually confused with natural and cultural tourism.CBET is fast becoming a popular biodiversity conservation tool that develops and benefits the local community. Based on the context of conservation theory and practice, Community-Based Ecotourism (CBET) is a form of community-based natural resource management. However, a sustainable CBET development through Community Capacity Building (CCB)programs is not something that it easily achievable. Local community’s capacity varies from one culture to another. It takes a high level of community participation, in order for it to come to a level where the community members themselves are motivated to participate and contribute to the development of the program. This fully qualitative research involved 15 respondents from the community of Kg. Selai, Bekok in Johor, Malaysia. The result show there are five factors that sustained the ecotourism development based for Orang Asli Community in Kg. Selai, namely, existing CBET development, past CBET development, local community participation in planning stage of tourism, local participation in implementation stage of tourism and participation in nature conservation
Corrosion study of pipeline material for seabed sediment in tropical climate
Corrosive environments such as marine sediments can cause corrosion to
steel pipelines at any time when certain conditions are met. Seabed sediment could cause severe corrosion damage due to its corrosiveness to the pipelines buried under it. Many consequences could take place in case if there is incident in oil/gas pipelines. Successfully identifying elements of corrosion in marine sediment would enhance the future of steel structure protection and monitoring systems. This article focuses on the behaviour of corrosion rate of steel located near shore environment and the aim is to determine the effect of sediment on corrosion of steel. To investigate that, simulated near shore sediment conditions have been used where the steel coupons buried in sediments which have different characteristics. Weight loss technique has been implemented to determine the weight loss rate of the steel specimens. Based on the
results of this study, metal weight loss increases as the duration of exposure to seabed sediment environment become longer. The sea sediment simulated condition has given significant levels of corrosion. Conclusively, the corrosion rate of steel in seabed sediment located in tropical region is complicated and further studies are suggested
Lossy/Lossless Floating/Grounded Inductance Simulation Using One DDCC
In this work, we present new topologies for realizing one lossless grounded inductor and two floating, one lossless and one lossy, inductors employing a single differential difference current conveyor (DDCC) and a minimum number of passive components, two resistors, and one grounded capacitor. The floating inductors are based on ordinary dual-output differential difference current conveyor (DO-DDCC) while the grounded lossless inductor is based one a modified dual-output differential difference current conveyor (MDO-DDCC). The proposed lossless floating inductor is obtained from the lossy one by employing a negative impedance converter (NIC). The non-ideality effects of the active element on the simulated inductors are investigated. To demonstrate the performance of the proposed grounded inductance simulator as an example, it is used to construct a parallel resonant circuit. SPICE simulation results are given to confirm the theoretical analysis

Neuro-Protection and Neuro-Therapy Effects of Acalypha Indica Linn. Water Extract Ex Vivo on Musculus Gastrocnemius Frog
The studies of neuro-protection and neuro-therapy effects of Acalypha indica Linn. water extract ex vivo on Musculus gastrocnemius frog have already done at three Departments in Faculty of Medicine, University of Indonesia. The experimental studies were done on 2 groups of frog for neuro-protection and neuro-therapy effects. Each group of frog was divided into 7 subgroups of application, 4 samples each. There were 5 subgroups of doses: 5; 10; 15; 20; 25 mg and 2 subgroups as control. Pancuronium bromide 0.2%, 4 mg, was used for a positive control as muscle relaxant. Neuro-protection study was done as follow: ringer – extract – pancuronium bromide, and neuro-therapy study was ringer – pancuronium bromide – extract, respectively. The parameters measured in these studies were the electrical activities such as amount and duration (second) of re-polarization; depolarization, resting potential, and the height of spike after electrical stimulation at 5 mV. Neuro-protection effect of extract was determined by the ability of muscle to show the electrical response after incubating with pancuronium bromide for 10 minutes, and after incubating with extract for 10 minutes for neuro-therapy effect. In the dose of 15 mg and 20 mg/mL of A. indica Linn. extract showed better activities than the dose of 25 mg of extract, both as neuro-protection and neuro-therapy effects, but statistically its have not a significant difference. This study should be followed by an in vivo experiment on frog and it would be done in pharmacokinetic and pharmacodynamic studies on other animal models
Perception Analysis of Silver Jubilee Grade-Separated Intersection in Kano Metropolis Using Context Sensitive Solutions
This study explores the users’ perception on operational performance of Silver Jubilee Grade Separated Intersection (SJGSI) in Kano Metropolis using Context Sensitive Solutions (CSS). The CSS seeks to provide a transportation facility that fits its setting, leading to the preservation and enhancement of scenic, aesthetic, environmental and community resources while maintaining safety, mobility and comfort. A structured questionnaire enquired the opinion of respondents, among others, on the optimal performance of SJGSI and its determinants. Three correlation analyses and two regression analyses were generated. The results showed that most of the correlating and regressing variables are weakly correlated by chance. The degree of familiarity correlated with number of motorists (users) has an R-value of 0.125; the optimal performance correlated with its cost worthiness has an R-value of 0.166. The general and Context Sensitive (CS) optimal performance model has an R-values of 0.415 and 0.374, respectively. Some of the weak correlations could be attributed to the facility not planned based on CSS approach. A CS facility could have received a higher optimal performance rating, approval rating and CS features’ rating with increased efficiency and effectiveness. Most respondents opined that a better facility would have been constructed if all relevant stakeholders were involved in the development processes
