Expansion of a hexanucleotide (GGGGCC) repeat in the gene chromosome 9 open reading frame 72 (C9ORF72) is the most common cause of amyotrophic lateral sclerosis and frontotemporal dementia (FTD). Three non-exclusive mechanisms have been proposed to contribute to the pathology initiated by this genetic insult. First, it was suggested that decreased expression of the C9orf72 protein product may c...

We contrast in this article the system demands imposed by brute force, complete replanning and a new, goal-directed approach called dynamic plan revision (DPR). One of the two processes must be invoked when some aspects of the environment change and currently existing plans are likely to fail. Complete replanning is conceptually simpler but requires significantly more computation because it rep...

Temporal performance parameters vary across the visual field. Their topographical distributions relative to each other and relative to basic visual performance measures and their relative change over the life span are unknown. Our goal was to characterize the topography and age-related change of temporal performance. We acquired visual field maps in 95 healthy participants (age: 10-90 years): p...

AbstractPressure relief valve is one of the most important devices used on the security of pipelines, since it is responsible to guarantee the integrity of the installations. Generally, the response and behaviour of a relief valve during its transient is unknown by users, who employ simplified and static analysis to design the pipeline, further, the information provided by manufactures is limit...

Thanks to their flexibility, FPGAs are nowadays widely used to implement digital systems’ prototypes and, more frequently, their final releases. Reconfiguration traditionally required an external controller to upload contents in the FPGA. Dynamic Partial Reconfiguration (DPR) opens new horizons in FPGAs’ applications, providing many new utilization paradigms, as it enables an FPGA to reconfigur...

Face recognition is important in human identification. The biological recognition technique acts as a good method and broad applications in security areas. This work presents a method to improve the face recognition accuracy using a combination of Principal Component Analysis (PCA), and Wavelet Transform. Wavelet Transform is used to decompose the input image with different levels and rearrange...

Abstrak: Data memiliki peran penting dalam pengambilan keputusan strategis. Oleh karenanya, pihak yang mampu mengolah dan memanfaatkan data-data tersedia volume besar, keragaman variatif, kompleksitas tinggi kecepatan penambahan data tinggi, dapat mengambil keuntungan besar. Penggunaan metode prototyping di penelitian ini bertujuan agar peneliti mendapatkan gambaran aplikasi akan dibangun melal...

In a statistical study of the decay of individual sunspots based on DPR data we find that the mean instantaneous area decay rate is related to the spot radius r and the maximal radius r0 as D = CD r/r0, CD = 32.0±0.26MSH/day. This implies that sunspots on the mean follow a parabolic decay law; the traditional linear decay law is excluded by the data. The validity of the Gnevyshev–Waldmeier rela...

Textures often show multiscale properties and hence multiscale techniques are considered useful for texture analysis. Scale-space theory as a biologically motivated approach may be used to construct multiscale textures. In this paper various ways are studied to combine features on different scales for texture classification of small image patches. We use the N-jet of derivatives up to the secon...
