i have ontology like: :indi_1 :segment; [ :builds {:indi_2}]; :hasid 1. now want find individual(s) indi_1 builds. made following query: select distinct ?a {:indi_1 ?b. ?b _:blanknode} but still segment in results. plus can't reach inside blank node retrive indi_2 . how should build query? i don't know why you'd expect ?b :blanknode require ?b blank node. :blanknode blank node, in sparql query acts variable, it's requiring ?b has type. query written isn't legal. looks want :indi_1 ?b . ?b _:blanknode instead (note . , not ; ). at rate, check whether blank node, @ sparql 1.1 spec , , notice there's isblank function. that's you'd use filter results. you'd have this: select * { ?a ?b filter isblank(?b) } but if you're looking list of individuals, need bit more closely @ rdf serialization of data. don't care ?b blank, rather it's restriction right properties. axiom like:      :a builds {:b, :c

i trying output status of connection after open connection , after close it. getting output of 1 when open , 2 when close it, there no talk these values mean in psycopg2's documentation. know different status values mean? i using status function connection status values. those documented status constants , can find them here: http://initd.org/psycopg/docs/extensions.html#connection-status-constants this not tell numeric representation/value of it, though. if print each constant, did, should this: from psycopg2 import extensions ext print(ext.status_ready) #1 print(ext.status_begin) #2 print(ext.status_in_transaction) #2 (this alias status_begin) print(ext.status_prepared) #5 note documentation states: "the status undefined closed connectons (sic) ." http://initd.org/psycopg/docs/connection.html#connection.status

i working on algorithm requires calculations in large numbers, upto e+30. using 32 bit system compiler support of 32 bits long/float/double. far, searching online, i've learned single-precision floating points (fps) can used double-precision fps. from question asked earlier ( emulate “double” using 2 “float”s ) found paper has algorithm work double-precision fps in gpus. confusing me implement in c. need 4 basic mathematical operations. there way find example me understand better? thanks in advance. here code working on. might have errors can not see, suggestions appreciated rectify error preety trying implement. in algorithm, polynomial_order should able go forth order (can settle @ third order if standard deviation smaller). few things not sure 1) procedures make_float() , make_float() correct or not, 2) use of make_float() in program. #define polynomial_order (3) #define tc_table_size (14) typedef struct vector_float2{ float x; float y; }float2; typedef struct
