Abstract Continuous control protocols are extensively utilized in traditional MASs, in which information needs to be transmitted among agents consecutively, therefore resulting in excessive consumption of limited resources. To decrease the control cost, based on ISC, several LFC problems are investigated for second-order MASs without and with time delay, respectively. Firstly, an intermittent sampled controller is designed, and a sufficient and necessary condition is derived, under which state errors between the leader and all the followers approach zero asymptotically. Considering that time delay is inevitable, a new protocol is proposed to deal with the time-delay situation.… More >

Abstract In response to the problem of frequent leakage and false alarm of partial discharge insulation defects in GIS, this paper conducts experimental research on intermittent discharge characteristics of common solid insulation defects in GIS. Using true GIS to build a multi-source testing platform for intermittent discharge of solid insulation defects, and using pulse current method, ultra-high frequency method, ultrasonic method, and gas characteristic component detection method to study the variation law of intermittent discharge characteristics of solid insulation defects. The results show that: the intermittent discharge state of metal fouling defects on the solid insulation… More >

Abstract In the hot summer & cold winter zone in China, intermittent heating space for rooms is widely used. However, in comparison with continuous space heating, the energy-saving performance of intermittent space heating has not been sufficiently investigated. This paper studied the factors influencing the energy performance of intermittent heating for the representative office in hot summer & cold winter zone. Based on the heat balance method, a dynamic thermal model of the intermittent heating room was built and tested by experiments. And then, it analyzed the total space heating load, the amount of energy saving… More >

Abstract This paper presents a new optimization study of the placement and size of a photovoltaic source (PVS) in a distribution grid, based on annual records of meteorological parameters (irradiance, temperature). Based on the recorded data, the production output as well as the daily average power (24-h vector) of the PVS is extracted over the year. When a power vector is available, it can be used as an input when searching for the optimal size of the PVS. This allows to take into account the constraint of the variation of the power generated by this source More >

Abstract Introduction: Urinary Tract Infection (UTI) has been cited as the primary cause of morbidity in patients with a history of spinal cord injury (SCI). Despite the significance of recurrent UTI (rUTI) in this population, the causative physiologic and patient characteristics are not well described. We sought to assess associations between demographic, clinical, and urodynamic variables and rUTI.
Materials and methods: The records of 136 individuals with SCI who perform clean intermittent catheterization (CIC) were retrospectively reviewed. All had a video urodynamics study (VUDS) available for analysis. Individuals were divided into non-recurrent (< 3/year) or rUTI (≥ 3/year)… More >

Abstract The randomness of rock joint development is an important factor in the uncertainty of geotechnical engineering stability. In this study, a method is proposed to evaluate the reliability of intermittent jointed rock slope. The least squares support vector machine (LSSVM) evolved by a bacterial foraging optimization algorithm (BFOA) is used to establish a response surface model to express the mapping relationship between the intermittent joint parameters and the slope safety factor. The training samples are obtained from the numerical calculation based on the joint finite element method during this process. Considering the randomness of the… More >

Abstract Introduction: We sought to investigate whether starting clean intermittent catheterization (CIC) for multiple sclerosis (MS) patients with lower urinary tract symptoms (LUTS) and elevated post-void residual (PVR) would improve urinary quality of life (QoL) and decrease risk of urinary tract infection (UTI).
Materials and methods: We retrospectively reviewed an institutional database for MS patients with PVR > 100 mL and obstructive LUTS. Patients were categorized by subsequent choice of treatment: CIC versus medical treatment. Outcomes compared over 1-year follow up included incidence of UTI, urinary QoL, emergency room visits, and adherence to therapy.
Results: Between 2014 and 2017,… More >

Abstract instruction: Introduction: Intermittent androgen deprivation therapy (IADT) for prostate cancer involves cycles of androgen deprivation therapy (ADT) with a period between cycles where testosterone is allowed to rise above castrate levels. A number of recent randomized controlled trials (RCTs) have compared survival and health-related quality-of-life (HRQOL) between IADT and continuous ADT (CADT). This review seeks to critically analyze these published trials for their relevance to clinical practice.
instruction: Materials and methods: Published trials were retrieved from a systematic search of MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials databases using relevant keywords. Recent systematic reviews… More >

Abstract Introduction: Clean intermittent catheterization (CIC) theoretically reduces incontinence, urinary tract infections (UTIs) and lower urinary tract symptoms (LUTS) in the face of poor emptying. It is unclear whether all patients realize these benefits or if CIC is only helpful for some.
Materials and methods: A retrospective review of 321 patients all of whom underwent urodynamic study prior to starting CIC for impaired emptying. Success was considered to be no incontinence, no UTIs, and no LUTS while performing CIC. Patients who did not meet these criteria or who stopped CIC for whatever reason were classified as failures.
