Channel shortening equalizers for UWB receiver design simplification
… of this thesis is to propose channel shortening or time domain equalization as a technique to reduce the complexity of the UWB Rake receiver. It is analyzed that most of the existing channel shortening equalizer (CSE) designs are either system specific or optimize a parameter not …

Comparing fatigue induced by isometric and shortening contractions in skeletal muscle
… fatigue-induced reduction in force during shortening compared with isometric contractions is not completely understood. The focus of this thesis was to compare fatigue in repeated shortening contractions and isometric contractions and investigate if greater force loss during repeated …

The shortening of the work week as a component of economic growth
This thesis, as its title indicates, deals primarily with the economic aspects of shorter hours. The emphasis throughout the thesis is upon economic principles combined with explanatory factual material. With labor issues on the front pages of newspapers, the reader may acquire many miscellaneous …

Determining muscle-tendon characteristics and function of stretch-shortening cycle performance in dancers
… muscle-tendon unit (MTU) properties and stretch-shortening cycle (SSC) proficiency. Early on in athletic development, dancers are instructed to maintain aesthetic posture, wherein the hips are directly beneath the shoulders, during most jumps and leaps. Different from a countermovement jump, …

Telomere Structure and Shortening in Telomerase-Deficient Trypanosoma brucei: Implications for Anitgenic Variation
… parasites exhibited progressive telomere shortening at a rate of 3—6 bp/PD, which correlates with the end replication problem and G-overhang length. Upon reaching a critical length, short silent ES telomeres stabilized. Telomere decline was accompanied by loss of minichromosomes and …

The Relationship Between Torque and IEMG During Proportional Shortening of the Biceps Brachii Muscle
… between torque and IEMG during proportional shortening of the biceps brachii muscle where the angular displacement to each subject was based upon the resting length of their muscle. Thirty male subjects participated in the investigation after giving informed consent. The results of the …

Speed Through Flexibility: Shortening the Acquisition Timeline of U.S. Defense Capabilities Using Flexible Systems
Military procurement projects face a fundamental dilemma: systems designed and built today must serve the needs of the future, but future needs cannot be reliably forecasted. This reality drives the U.S. defense acquisition system, which creates and maintains defense capabilities in a constantly …

Effect of flour protein content on the utilization of shortening and cellulose in biscuits
… and 10.05% protein with 30, 40, and 50 grams of shortening and 0 or 2.2 grams of microcrystalline cellulose (MCC). Biscuit quality was assessed by objective and sensory evaluation. The caloric content of the biscuits was also determined by bomb calorimetry. No significant differences were …

Evaluating Stretch-Shortening Cycle Function in Athletes After ACL Reconstruction Using a Repeat Hop Test
The purpose of this thesis was to evaluate the influence of external task constraints on repeat hop testing (RHT) performance, neuromuscular control, and interlimb force-time asymmetry in athletes following anterior cruciate ligament reconstruction (ACLR). The first study compared three methods for …

Motor unit firing rate control of agonist skeletal muscle during voluntary isometric and shortening contractions with limb movement
Voluntary movements throughout mammalian lifespan require skeletal muscle contractions that are controlled by time- and recruitment-dependent firing rate patterns. Single motor unit (MU) activity reflects the final efferent neural drive to the muscle, yet the underlying neural control of movement …

Stretch-Shortening Cycle in Human Muscle Contraction: The Role of the Stretch Reflex in Force Production in Various Vertical Jumps
… relative to elasticity in the stretch-shortening contraction of the vastus lateralis muscle during the following vertical jumps: counter-movement jump (CMJ), counter-movement hop (CMH), drop jump (DJ), squatting jump tense (SJT), squatting jump rested (SJR), and squatting jump hop …

Impact of Sex and Stretch-Shortening Cycle Induced-Fatigue on Limb Stiffness and Limb Stiffness Asymmetry During the Stop-Jump
… effect of sex and fatigue induced by the stretch-shortening cycle on lower limb mechanics and asymmetry values in the stop-jump task. The first purpose of the study was to assess the effect of sex and stretch-shortening cycle fatigue on limb stiffness and limb stiffness asymmetry. The second …

Speech Rhythm in American English: A Corpus Study
… News corpus, comparing the patterns of rhythmic shortening in two different types of prosodic domains, the ISI (inter-stress interval) and the IAI (inter-accent interval). The main finding is evidence for rhythmic shortening in the domain defined in terms of lexical stress: the duration of vowels …
