present study was conducted in the three provinces of pakistan with the objectives to study the curricula relevancy with the participatory extension, supervision and administration and its practical applicability at the field level. for this extension agents of the selected provinces were selected purposively. mail questionnaire were used as instruments for data collection form 227 respondents ...

this study examined the accuracy between extension professionals and farmers regarding their perceptions of privatization and commercialization of agricultural extension services. the study was carried out in delta state, nigeria and it had a sample size of 224 respondents comprising of 134 extension professionals of the delta state agricultural programme (dtadp) and 90 farmers that were random...

Fig. 1. Multi-slice ECG-gated CT scan (slice thickness, 1.25 mm). (A) Contrast enhanced axial image, the right pulmonary artery was completely occluded by a mass (arrowhead). Endovascular component and extension into the surrounding pulmonary parenchyma were well shown. (B) 3D volume-rendered reconstruction (oblique view) shows the extension (arrowheads) and bronchial artery hypertrophy (arrows...

The formal speciication language LOTOS is an international standard for use in Open Systems Interconnection. A timed extension called ET-LOTOS has been proposed. This paper presents a fully-abstract denotational semantics for the process algebraic component of this extension. The beneets of a denotational semantics are discussed, as are the applications.

Software entities should be open for extension, but closed to modification. Unfortunately, unanticipated requirements emerging during software evolution makes it difficult to always enforce this principle. This situation poses a dilemma that is particularly important when considering component-based systems: On the one hand, violating the open/closed principle by allowing for modification compr...

Hazard and Operability (HazOp) and Fault Tree Analyses (FTA) are embedded into UML component models. The latter are constructed by employing UML's extension mechanisms in conjunction with component-based software techniques. Taking an application's safety-related requirements into consideration, the elements of HazOp and FTA are defined as component attributes, and assigned to a UML component m...

Based on latest achievements in the field of Component Based Design (CBD) and Component Oriented Programming (COP), this article shows how a component lifecycle can be extended. The well-known Hierarchical Model View Controller (HMVC) design pattern is considered for the identification of the two concerns Showable and Loadable Following, these two concerns are added to a component to demonstrat...

Malrotation of the femoral component may cause patellofemoral complications after total knee replacement (TKR). We hypothesized that femoral component malrotation would cause excessive lengthening of the retinacula. Retinacular length changes were measured by threading fine sutures along them and attaching these to the patella and to displacement transducers. The knee post-TKR was flexed-extend...

This paper discusses an algorithm to automate the generation of constraints files by leveraging a simple extension to the device characteristic model. This extension consists of additional pin-level restriction data that defines the test constraints. While additional constraints based on the unique features of the design may still be required, the component-based constraints can be quickly dete...

In this paper, we introduce a new method of data transformation for finger vein recognition system. Our proposed method uses kernel mapping functions to map the data before performing Principal Component Analysis. Kernel Principal Component Analysis (KPCA) is a well-known extension of PCA which is suitable for finding nonlinear patterns as it maps the data nonlinearly. In this work we develop a...
