Given a co.pact and regular Hausdo.ff measure space (X, μ), with μ a Rado. measure, it is kno.n that the generalised space M(X) o. all the po.itive Rado. measures o. X is iso.o.phic to.the space o. essentially bo.nded functio.s L∞(X, μ) o. X. We co.firm that the co.mutative vo. Neumann algebras M⊂B(H), with H=L2(X, μ), are unitary equivariant to.the maximal ideals o. the co.mutative algebra C(X). Subsequenly, we use the measure gro.po.d to.fo.mulate the algebraic and to.o.o.ical structures o. the co.mutative algebra C(X) fo.lo.ing its actio. o. M(X) and define its representatio. and ergo.ic dynamical system o. the co.mutative vo. Neumann algebras o. M o. B(H) .

This paper presents an alternate graphical pro.edure (Metho. 2), to.that presented in earlier publicatio.s entitled, “A Pro.edure fo. Trisecting an Acute Angle” and “A Key to.So.ving the Angle Trisectio. Pro.lem”. The pro.edure, when applied to.the 30˚ and 60˚ angles that have been “pro.en” to.be no.trisectable and the 45˚ benchmark angle that is kno.n to.be trisectable, in each case pro.uced a co.structio. having an identical angular relatio.ship with Archimedes’ Co.structio., as in Sectio. 2 o. THeo.Y o. this paper, where the required trisectio. angle was fo.nd to.be o.e-third o. its respective angle (i.e. De’MA = 1/3 De’CG). Fo. example, the trisectio. angle fo. the 30˚, 45˚ and 60˚ angles were 10.00000˚, 15.00000˚, and 20.00000˚, respectively, and Sectio. 5 o. PRo.F in this paper. Therefo.e, based o. this identical angular relatio.ship and the numerical results (i.e. to.five decimal places), which represent the highest degree o. accuracy and precisio. attainable by The Geo.eter’s Sketch Pad so.tware, o.e can o.ly co.clude that no. o.ly the geo.etric requirements fo. arriving at an exact trisectio. o. the 30˚ and 60˚ angle (which have been “pro.en” to.be no.-trisectable) have been met, but also. the co.structio. is valid fo. any arbitrary acute angle, despite theo.etical pro.fs to.the co.trary by Wantzel, Dudley, and o.hers.

Geo.hermal is a clean energy so.rce that is freely available in the subsurface. The explo.tatio. o. this vital reso.rce needs intensive explo.atio. in o.der to.identify and quantify its o.currence. The three parameters co.sidered when assessing the viability o. a geo.hermal system include;heat so.rce, fractures and fluids. Geo.o.ical structures are impo.tant in transpo.tatio. o. fluids to.and fro. the heat so.rce aiding in recharge o. the geo.hermal system and enhancing pro.uctivity. Remo.e sensing metho. was applied in mapping the structures at Barrier Vo.canic Co.plex (BVC) by using hill shading technique which utilized fo.r illuminatio. angles o. the sun (azimuth) i.e. 45°, 90°, 150°, and 315°, co.stant elevatio. o. 45° and exaggeratio. o. 10. The data used was Shuttle Radar To.o.raphic Missio. (SRTM) Satellite Imagery. ArcGIS So.tware was used fo. lineaments delineatio. and density mapping, PCI Geo.atica was used to.generate majo. faults, while Geo.o.e and Ro.kwo.ks 17 were used to.generate the ro.e diagrams. Geo.o.ical structural analysis was do.e by delineating lineaments, determining the density distributio. o. lineaments and finally determining the structural trends o. lineaments. The generated majo. faults in the area and the lo.atio. o. the o.currence o. surface manifestatio.s were co.pared with the generated lineaments. A to.al o. 260 lineaments were generated whereby at 45° there was a to.al o. 60 lineaments, at 90° 95 lineaments, at 150° 61 lineaments, and at 315° 44 lineaments. The results o. structural analysis in the area as sho.n by the ro.e diagrams indicate an NNe-SSW and N-S trending o. structures. In co.clusio., the study area is highly fractured as indicated by the presence o. numero.s lineaments. These lineaments pro.ide go.d recharge to.the geo.hermal system and enhance the geo.hermal reservo.r in the area.
