Motivation: Understanding which parts of an image belong to a “foreground” object and which belong to the “background” can provide information potentially useful for object recognition. A recent physiology experiment [5] has shown that neurons along the visual stream (areas V2 and V4) carry information about how local features belong to objects. Very interestingly, this modulation of neuronal f...

This paper presents a brain inspired neural architecture with spatial cognition and navigation capability. The brain inspired system is mainly composed of two parts: a bio-inspired hierarchical vision architecture (HMAX) and a hippocampal-like circuitry. The HMAX encodes vision inputs as neural activities and maps to hippocampal-like circuitry which stores this information. Sensing a similar ne...

In this paper, an efficient implementation for a recognition system based on the original HMAX model of the visual cortex is proposed. Various optimizations targeted to increase accuracy at the so-called layers S1, C1, and S2 of the HMAX model are proposed. At layer S1, all unimportant information such as illumination and expression variations are eliminated from the images. Each image is then ...

Specification of realistic environmental design conditions for marine structures is of fundamental importance to their reliability over time. Design conditions for extreme waves and storm severities are typically estimated by extreme value analysis of time series of measured or hindcast significant wave height, HS. This analysis is complicated by two effects. Firstly, HS exhibits temporal depen...

Upper extremity (UE) hemiparesis persists after stroke, limiting hand function. Neuromuscular electrical stimulation (NMES) is an effective intervention to improve UE recovery, although the underlying mechanisms are not fully understood. Our objective was to establish a reliable protocol to measure UE agonist-antagonist forearm monosynaptic reflexes in a pilot study to determine if NMES improve...

Reliable tree height-diameter (H-D) allometric equations are a key tool for the estimation of forest productivity and Above Ground Biomass (AGB). Most existing H-D developed tropical region based on large-scale multi-species datasets, their use to derive information AGB at species level is prone uncertainties. The single-species available mainly focused monocultures or stands with simple mixtur...

This study investigated flow characteristics and heat transfer enhancement in various sinusoidal corrugated channels. The channel height the phase shift effects on structures thermal performances were examined numerically for Reynolds numbers range of 2500≤Re≤7500. geometrical configurations this cover three different heights (Hmin/Hmax=0.36, 0.54, 0.72) angles (φ=0°, 90°, 180°). Velocity distr...

The purpose of this study was to investigate the validity of the modified Ashworth Scale (MAS) by using both the conventional (Hmax/Mmax ratio) and the new indicators (Hslp/Mslp) of motoneuron excitability. This research was a correlational study on twenty post-stroke patients. Main outcome measures were the MAS and electrophysiologic assessments. The latter was performed using both conventiona...

The group mutual exclusion problem is an extension of the traditional mutual exclusion problem in which every critical section is associated with a type or a group. Processes requesting critical sections of the same type can execute their critical sections concurrently. However, processes requesting critical sections of different types must execute their critical sections in a mutually exclusiv...

This paper explores the relative accuracy of deriving solar EUV flux, exospheric temperature Tex, and meridional winds using complete altitude profiles of ionosphere electron density as compared to just using key parameters such as Nmax, hmax and ionospheric electron content. Incoherent scatter radar observations at Millstone Hill and Shigaraki and an ionospheric model are used in this study. W...
