We connect two seemingly unrelated problems in graph theory. Any graph G has a neighborhood multiset N (G) = {N(x) | x ∈ V (G)} whose elements are precisely the open vertex-neighborhoods of G. In general there exist non-isomorphic graphs G and H for which N (G) = N (H). The neighborhood reconstruction problem asks the conditions under which G is uniquely reconstructible from its neighborhood mu...

The study presents analytical, simulation, and experimental analyses of amplitude cancellation of motor-unit action potentials (APs) in the interference electromyogram (EMG) and its relation to the size of the spike-triggered average (STA) EMG. The amount of cancellation of motor-unit APs decreases monotonically as a function of the ratio between the root mean square (RMS) of the motor-unit AP ...

We used variations of the stop signal task to study two components of motor response inhibition-the ability to withhold a strong response tendency (restraint) and the ability to cancel an ongoing action (cancellation)-in children with a diagnosis of attention deficit hyperactivity disorder (ADHD) and in non-ADHD controls of similar age (ages 7-14 years). The goal was to determine if restraint a...

Form the past several decades' noise cancellation in speech signal gains researchers' attention. Several techniques were developed for noise cancellation among them optimal wiener filter can be the one of the most fundamental approach for noise cancellation. Later on adaptive filter was introduced to attain better performance. This paper shows the capacity of wiener filter and adaptiv...

This paper explains about the mud for CDMA and compares different techniques available in the same field and comes out with the most effective approach. A brief explanation about interference cancellation, decorrelator mud and successive interference cancellation have been emphasized

The success of awake craniotomies relies on the patient's performance of function-specific tasks that are simple, quick, and reproducible. Intraoperative identification of visuospatial function through cortical and subcortical mapping has utilized a variety of intraoperative tests, each with its own benefits and drawbacks. In light of this, we developed a simple software program that aids in pr...

Analog systems to achieve active noise cancellation in headphones were designed and implemented. Our project addresses two distinct technqiues feed forward and feedback systems. The work up to mid-semester, which was focused mainly on a feed-forward system with the motivation of developing a clip-on platform for generic earphones, is presented briefly. Limitations of this approach that lead to ...

Echo in the telephone network is a well-known phenomenon -long delays and noticeable echo may create significant or even unbearable disturbance in a telephone conversation. Echo cancellation is a technique to reduce the echo to an acceptable level. In fact, network echo canceller is considered as the single most critical element impacting overall voice quality in typical communication networks....

We give here a mathematical context for polynomial cancellation coding, proposed recently to reduce intercarrier interference in orthogonal frequency division multiplexing (OFDM). In particular, we analyze polynomial cancellation coding (PCC) in terms of finite differences.
