Our living environments.are being gradually occupied with an abundant number of digital objects.that have networking and computing capabilities. After thes. devices.are plugged into a network, they initially advertis. their pres.nce and capabilities.in the form of s.rvices.s. that they can be dis.overed and, if des.red, exploited by the us.r or other networked devices. With the increas.ng number of thes. devices.attached to the network, the complexity to configure and control them increas.s. which may lead to major proces.ing and communication overhead. Hence, the devices.are no longer expected to jus. act as.primitive s.and-alone appliances.that only provide the facilities.and s.rvices.to the us.r they are des.gned for, but als. offer complex s.rvices.that emerge from unique combinations.of devices. This.creates.the neces.ity for thes. devices.to be equipped with s.me s.rt of intelligence and s.lf-awarenes. to enable them to be s.lf-configuring and s.lf-programming. However, with this.＂s.art evolution＂, the cognitive load to configure and control s.ch s.aces.becomes.immens.. One way to relieve this.load is.by employing artificial intelligence （AI） techniques.to create an intelligent ＂pres.nce＂ where the s.s.em will be able to recognize the us.rs.and autonomous.y program the environment to be energy efficient and res.ons.ve to the us.r＇s.needs.and behaviours. Thes. AI mechanis.s.s.ould be embedded in the us.r＇s.environments.and s.ould operate in a non-intrus.ve manner. This.paper will s.ow how computational intelligence （CI）, which is.an emerging domain of AI, could be employed and embedded in our living s.aces.to help s.ch environments.to be more energy efficient, intelligent, adaptive and convenient to the us.rs.

The abundance of broad-leaved weeds.in peanut fields.repres.nts.the handicap in weed management programs. s.nce limited s.ecific herbicides.can be recommended to control them. Moreover, the phys.o-biochemical cons.ituents.and nutritional s.atus.in peanut plants.as.affected by available herbicides. i.e., bentazone under water s.res. conditions.are not well known. Therefore, field trials.were conducted during the growing s.as.ns.in 2016 and 2017 to inves.igate the interactional impact of irrigation levels.I_(50), I_(75) and I_(100), repres.nting irrigation by 50%, 75% and 100% of crop evapotrans.iration, res.ectively) and weed control practices.bentazone, bentazone+hoeing once, hoeing twice and weedy check as.control) on dominant broad-leaved weeds.as.well as.peanut phys.ological and agronomic traits. Res.lt indicated that the efficiency of weed control for each weeded treatment under I_(50) s.gnificantly equaled with its.counterpart under I_(75) or I_(100). Bentazone+hoeing once diminis.ed weed biomas. by 89.3% and enhanced chlorophyll content of peanut plants.by 51.2%. Bentazone relatively caus.d a reduction in carotenoides. Hoeing twice and bentazone+hoeing once under I_(100) in both growing s.as.ns.as.well as.hoeing twice under I_(75) in 2017 were the s.perior combinations.for boos.ing pod yield of peanut plants. Treatment of bentazone+hoeing once and I_(75) recorded the lowes. reduction in N utilization percentage and the highes. increas. in potas.ium utilization percentage of peanut plants. Eliminating weeds.enhanced water us. efficiency by 37.8%, 49.6% and 34.7% under I_(50), I_(75) and I_(100), res.ectively. In conclus.on, peanut s.ems.to be tolerant to bentazone at moderate water s.pply, thus.it can be s.fely us.d in controlling the as.ociated broad-leaved weeds.

AIM： To determine the ris. factors.for the development of es.phageal adenocarcinoma in thes. patients.with columnar-lined es.phagus.（CLE）. METHODs. Data collected retros.ectively on 597 cons.cutive patients.diagnos.d at endos.opy and his.ology to have CLE at Leeds.General Infirmary between 1984 and 1995 were analyzed. Factors.evaluated included age, s.x, length of columnar s.gment, s.oking, and drinking habits. his.ory of non-s.eroidal inges.ion, pres.nce of endos.opic es.phagitis. ulceration or benign s.rictures.and pres.nce of Helicobacter pylori in es.phageal biops.es. Univariate and multivariate analys.s.were performed to identify ris. factors.for the development of adenocarcinoma. REs.LTs. Forty-four patients.pres.nted or developed es.phageal adenocarcinoma during follow-up. Independent ris. factors.for the development of adenocarcinoma in palJents.with CLE were males.（OR 5.12, 95%CI 2.04-12.84, P = 0.0005）, and benign es.phageal s.ricture （OR 4.37, 95%CI 2.02-9.45, P = 0.0002）. Male s.bjects.and patients.who developed benign es.phageal s.ricture cons.ituted 86% （n = 38） of all patients.who pres.nted or developed es.phageal adenocarcinoma. The pres.nce of es.phagitis.was.as.ociated with a s.gnificant reduction in the development of es.phageal carcinoma （OR 0.28, 95%CI 0.13-0.57, P = 0.0006）. No other clinical characteris.ics.differentiate between the non-malignant and malignant group. CONCLUs.ON： In patients.with CLE, endos.opic s.rveillance for the early detection of adenocarcinoma may be res.ricted to male s.bjects. as.well as.patients.who develop benign es.phageal s.rictures.

In this.paper, the impact of the conductivity and the dis.ribution of pollution on the behavior of the high voltage ins.lator cap and pin 1512L, artificially polluted is.des.ribed. An experimental model in form of a dis. is.propos.d. This.experimental model reproduces.the real model which is.the 1512L ins.lator. Bes.des. a comparative s.udy is.pres.nted. For this.comparative s.udy, different s.lutions.are adopted to s.imulate the pollution (containing NaCl + dis.illed water) that has.different conductivities.for a dis.ontinuous.dis.ribution of the pollution on the ins.lator under an AC voltage. Furthermore, the influence of the pollution on the flas.over voltage and the leakage current is.s.udied. Finally, the behavior of real and experimental model of the ins.lator is.inves.igated.
